fakecloud-codecommit 0.40.1

//! Account-partitioned, serializable state for AWS CodeCommit.
//!
//! A repository owns a content-addressed object store: `blobs` maps a 40-char
//! SHA-1 blob id to its (base64) bytes, and `trees` maps a commit id to the
//! full flat path -> [`FileEntry`] snapshot of that commit's working tree (a
//! materialized tree, so `GetFile`/`GetFolder`/`GetDifferences` are simple
//! lookups). `commits` maps a commit id to its stored `Commit`-shaped JSON, and
//! `branches` maps a branch name to the commit id at its tip. Pull requests,
//! comments, approval-rule templates and their associations, triggers, and tags
//! are stored as response-shaped JSON so a read returns exactly what was
//! written.
