Multi-line - comments using `///` are otherwise treated as an error, so use this - attribute or consider switching to block doc comments (`/** */`). - - - `#[prefix_enum_doc_attributes]` combines the doc comment message on - your enum itself with the messages for each variant, in the format - “enum: variant”. When added to an enum, the doc comment on the enum - becomes mandatory. When added to any other type, it has no effect. - -- In case you want to have an independent doc comment, the - `#[displaydoc("...")` atrribute may be used on the variant or struct to - override it. - -<br> - -### FAQ - -1. **Is this crate `no_std` compatible?** - * Yes! This crate implements the [`core::fmt::Display`] trait, not the [`std::fmt::Display`] trait, so it should work in `std` and `no_std` environments. Just add `default-features = false`. - -2. **Does this crate work with `Path` and `PathBuf` via the `Display` trait?** - * Yuuup. This crate uses @dtolnay's [autoref specialization technique](https://github.com/dtolnay/case-studies/blob/master/autoref-specialization/README.md) to add a special trait for types to get the display impl. It then specializes for `Path` and `PathBuf`, and when either of these types are found, it calls `self.display()` to get a `std::path::Display<'_>` type which can be used with the `Display` format specifier! - - -#### License - -<sup> -Licensed under either of <a href="LICENSE-APACHE">Apache License, Version -2.0</a> or <a href="LICENSE-MIT">MIT license</a> at your option. -</sup> - -<br> - -<sub> -Unless you explicitly state otherwise, any contribution intentionally submitted -for inclusion in this crate by you, as defined in the Apache-2.0 license, shall -be dual licensed as above, without any additional terms or conditions. -</sub> diff --git a/vendor/displaydoc/README.tpl b/vendor/displaydoc/README.tpl deleted file mode 100644 index 6206a9e7..00000000 --- a/vendor/displaydoc/README.tpl +++ /dev/null @@ -1,23 +0,0 @@ -derive(Display) /// `From<docs>` -=============== - -[](https://crates.io/crates/displaydoc) -[](https://docs.rs/displaydoc) - -{{readme}} - - -#### License - -<sup> -Licensed under either of <a href="LICENSE-APACHE">Apache License, Version -2.0</a> or <a href="LICENSE-MIT">MIT license</a> at your option. -</sup> - -<br> - -<sub> -Unless you explicitly state otherwise, any contribution intentionally submitted -for inclusion in this crate by you, as defined in the Apache-2.0 license, shall -be dual licensed as above, without any additional terms or conditions. -</sub> diff --git a/vendor/displaydoc/examples/simple.rs b/vendor/displaydoc/examples/simple.rs deleted file mode 100644 index f4aad213..00000000 --- a/vendor/displaydoc/examples/simple.rs +++ /dev/null @@ -1,36 +0,0 @@ -use displaydoc::Display; - -#[derive(Debug, Display)] -pub enum DataStoreError { - /// data store disconnected - Disconnect, - /// the data for key `{0}` is not available - Redaction(String), - /// invalid header (expected {expected:?}, found {found:?}) - InvalidHeader { expected: String, found: String }, - /// unknown data store error - Unknown, -} - -fn main() { - let disconnect = DataStoreError::Disconnect; - println!( - "Enum value `Disconnect` should be printed as:\n\t{}", - disconnect - ); - - let redaction = DataStoreError::Redaction(String::from("Dummy")); - println!( - "Enum value `Redaction` should be printed as:\n\t{}", - redaction - ); - - let invalid_header = DataStoreError::InvalidHeader { - expected: String::from("https"), - found: String::from("http"), - }; - println!( - "Enum value `InvalidHeader` should be printed as:\n\t{}", - invalid_header - ); -} diff --git a/vendor/displaydoc/src/attr.rs b/vendor/displaydoc/src/attr.rs deleted file mode 100644 index afda4b90..00000000 --- a/vendor/displaydoc/src/attr.rs +++ /dev/null @@ -1,137 +0,0 @@ -use proc_macro2::TokenStream; -use quote::{quote, ToTokens}; -use syn::{Attribute, LitStr, Meta, Result}; - -#[derive(Clone)] -pub(crate) struct Display { - pub(crate) fmt: LitStr, - pub(crate) args: TokenStream, -} - -pub(crate) struct VariantDisplay { - pub(crate) r#enum: Option<Display>, - pub(crate) variant: Display, -} - -impl ToTokens for Display { - fn to_tokens(&self, tokens: &mut TokenStream) { - let fmt = &self.fmt; - let args = &self.args; - tokens.extend(quote! { - write!(formatter, #fmt #args) - }); - } -} - -impl ToTokens for VariantDisplay { - fn to_tokens(&self, tokens: &mut TokenStream) { - if let Some(ref r#enum) = self.r#enum { - r#enum.to_tokens(tokens); - tokens.extend(quote! { ?; write!(formatter, ": ")?; }); - } - self.variant.to_tokens(tokens); - } -} - -pub(crate) struct AttrsHelper { - ignore_extra_doc_attributes: bool, - prefix_enum_doc_attributes: bool, -} - -impl AttrsHelper { - pub(crate) fn new(attrs: &[Attribute]) -> Self { - let ignore_extra_doc_attributes = attrs - .iter() - .any(|attr| attr.path().is_ident("ignore_extra_doc_attributes")); - let prefix_enum_doc_attributes = attrs - .iter() - .any(|attr| attr.path().is_ident("prefix_enum_doc_attributes")); - - Self { - ignore_extra_doc_attributes, - prefix_enum_doc_attributes, - } - } - - pub(crate) fn display(&self, attrs: &[Attribute]) -> Result<Option<Display>> { - let displaydoc_attr = attrs.iter().find(|attr| attr.path().is_ident("displaydoc")); - - if let Some(displaydoc_attr) = displaydoc_attr { - let lit = displaydoc_attr - .parse_args() - .expect("#[displaydoc(\"foo\")] must contain string arguments"); - let mut display = Display { - fmt: lit, - args: TokenStream::new(), - }; - - display.expand_shorthand(); - return Ok(Some(display)); - } - - let num_doc_attrs = attrs - .iter() - .filter(|attr| attr.path().is_ident("doc")) - .count(); - - if !self.ignore_extra_doc_attributes && num_doc_attrs > 1 { - panic!("Multi-line comments are disabled by default by displaydoc.

Multi-line -//! comments using `///` are otherwise treated as an error, so use this -//! attribute or consider switching to block doc comments (`/** */`). -//! -//! - `#[prefix_enum_doc_attributes]` combines the doc comment message on -//! your enum itself with the messages for each variant, in the format -//! “enum: variant”. When added to an enum, the doc comment on the enum -//! becomes mandatory. When added to any other type, it has no effect. -//! -//! - In case you want to have an independent doc comment, the -//! `#[displaydoc("...")` atrribute may be used on the variant or struct to -//! override it. -//! -//! <br> -//! -//! ## FAQ -//! -//! 1. **Is this crate `no_std` compatible?** -//! * Yes! This crate implements the [`core::fmt::Display`] trait, not the [`std::fmt::Display`] trait, so it should work in `std` and `no_std` environments. Just add `default-features = false`. -//! -//! 2. **Does this crate work with `Path` and `PathBuf` via the `Display` trait?** -//! * Yuuup. This crate uses @dtolnay's [autoref specialization technique](https://github.com/dtolnay/case-studies/blob/master/autoref-specialization/README.md) to add a special trait for types to get the display impl. It then specializes for `Path` and `PathBuf`, and when either of these types are found, it calls `self.display()` to get a `std::path::Display<'_>` type which can be used with the `Display` format specifier! -#![doc(html_root_url = "https://docs.rs/displaydoc/0.2.3")] -#![cfg_attr(docsrs, feature(doc_cfg))] -#![warn( - rust_2018_idioms, - unreachable_pub, - bad_style, - dead_code, - improper_ctypes, - non_shorthand_field_patterns, - no_mangle_generic_items, - overflowing_literals, - path_statements, - patterns_in_fns_without_body, - unconditional_recursion, - unused, - unused_allocation, - unused_comparisons, - unused_parens, - while_true -)] -#![allow(clippy::try_err)] - -#[allow(unused_extern_crates)] -extern crate proc_macro; - -mod attr; -mod expand; -mod fmt; - -use proc_macro::TokenStream; -use syn::{parse_macro_input, DeriveInput}; - -/// [Custom `#[derive(...)]` macro](https://doc.rust-lang.org/edition-guide/rust-2018/macros/custom-derive.html) -/// for implementing [`fmt::Display`][core::fmt::Display] via doc comment attributes. -/// -/// ### Generic Type Parameters -/// -/// Type parameters to an enum or struct using this macro should *not* need to -/// have an explicit `Display` constraint at the struct or enum definition -/// site.
