flakehub-cache-types

Nix store path, hash, and error types shared by FlakeHub Cache services.

The crate provides:

• nix_store::StorePath and nix_store::StorePathHash: parsed, validated store paths and their 32-character base name hashes.
• hash::Hash: SHA-256 hashes with Nix's base16 and base32 encodings.
• hash::Error: the parsing error returned by Hash::from_typed.
• StoreError and StoreResult: the errors returned by the store path operations above.

Usage

cargo add --git https://github.com/DeterminateSystems/flakehub-cache-types flakehub-cache-types

use flakehub_cache_types::nix_store::StorePathHash;

let hash = StorePathHash::new("ib3sh3pcz10wsmavxvkdbayhqivbghlq")?;

Features

• cxx (off by default): implements From<cxx::Exception> for StoreError, for use with C++ bindings to the Nix libraries.

Development

nix develop provides a Rust toolchain, and direnv loads it automatically. Run the tests with cargo test. CI enforces cargo fmt, cargo clippy, cargo deny, and editorconfig conformance.
