From 45df4d0d9b577fecee798d672695fe24ff57fb1b Mon Sep 17 00:00:00 2001 From: mo khan Date: Tue, 15 Jul 2025 16:37:08 -0600 Subject: feat: migrate from Cedar to SpiceDB authorization system This is a major architectural change that replaces the Cedar policy-based authorization system with SpiceDB's relation-based authorization. Key changes: - Migrate from Rust to Go implementation - Replace Cedar policies with SpiceDB schema and relationships - Switch from envoy `ext_authz` with Cedar to SpiceDB permission checks - Update build system and dependencies for Go ecosystem - Maintain Envoy integration for external authorization This change enables more flexible permission modeling through SpiceDB's Google Zanzibar inspired relation-based system, supporting complex hierarchical permissions that were difficult to express in Cedar. Breaking change: Existing Cedar policies and Rust-based configuration will no longer work and need to be migrated to SpiceDB schema. --- vendor/writeable/README.md | 57 ---------------------------------------------- 1 file changed, 57 deletions(-) delete mode 100644 vendor/writeable/README.md (limited to 'vendor/writeable/README.md') diff --git a/vendor/writeable/README.md b/vendor/writeable/README.md deleted file mode 100644 index 44138cd7..00000000 --- a/vendor/writeable/README.md +++ /dev/null @@ -1,57 +0,0 @@ -# writeable [![crates.io](https://img.shields.io/crates/v/writeable)](https://crates.io/crates/writeable) - - - -`writeable` is a utility crate of the [`ICU4X`] project. - -It includes [`Writeable`], a core trait representing an object that can be written to a -sink implementing `std::fmt::Write`.
