+# urlencoding
+
+[![Latest Version](https://img.shields.io/crates/v/urlencoding.svg)](https://lib.rs/crates/urlencoding)
+
+A tiny Rust library for doing URL percentage encoding and decoding. It percent-encodes everything except alphanumerics and `-`, `_`, `.`, `~`.
+
+When decoding `+` is not treated as a space. Error recovery from incomplete percent-escapes follows the [WHATWG URL standard](https://url.spec.whatwg.org/).
+
+## Usage
+
+To encode a string, do the following:
+
+```rust
+use urlencoding::encode;
+
+let encoded = encode("This string will be URL encoded.");
+println!("{}", encoded);
+// This%20string%20will%20be%20URL%20encoded.
+```
+
+To decode a string, it's only slightly different:
+
+```rust
+use urlencoding::decode;
+
+let decoded = decode("%F0%9F%91%BE%20Exterminate%21")?;
+println!("{}", decoded);
+// 👾 Exterminate!
+```
+
+To decode allowing arbitrary bytes and invalid UTF-8:
+
+```rust
+use urlencoding::decode_binary;
+
+let binary = decode_binary(b"%F1%F2%F3%C0%C1%C2");
+let decoded = String::from_utf8_lossy(&binary);
+```
+
+This library returns [`Cow`](https://doc.rust-lang.org/stable/std/borrow/enum.Cow.html) to avoid allocating when decoding/encoding is not needed. Call `.into_owned()` on the `Cow` to get a `Vec` or `String`.

+//!
+//! To decode a string, it's only slightly different:
+//!
+//! ```rust
+//! use urlencoding::decode;
+//!
+//! let decoded = decode("%F0%9F%91%BE%20Exterminate%21").expect("UTF-8");
+//! println!("{}", decoded);
+//! // 👾 Exterminate!
+//! ```
+//!
+//! To decode allowing arbitrary bytes and invalid UTF-8:
+//!
+//! ```rust
+//! use urlencoding::decode_binary;
+//!
+//! let binary = decode_binary(b"%F1%F2%F3%C0%C1%C2");
+//! let decoded = String::from_utf8_lossy(&binary);
+//! ```
+//!
+//! This library returns [`Cow`](https://doc.rust-lang.org/stable/std/borrow/enum.Cow.html) to avoid allocating when decoding/encoding is not needed. Call `.into_owned()` on the `Cow` to get a `Vec` or `String`.
