cesr

CESR + KERI primitives for Rust as a single feature-gated crate (modules: core/crypto/stream/utils/keri/serder). no_std/WASM-capable.

cesr consolidates six previously separate crates (cesr-utils, cesr-core, cesr-crypto, cesr-stream, keri-core, keri-serder) into one crate with independent feature gates per module. Public API paths are preserved verbatim — cesr_core::Matter becomes cesr::core::Matter. No behavior or signature changed in the extraction.

Modules & Features

Default features: ["std", "core", "utils"].

Usage

Published to crates.io as cesr-rs (the bare cesr name is taken) — the library is still imported as cesr:

[dependencies]
cesr-rs = { version = "0.1", features = ["keri", "serder"] }
# or, to keep the dependency key as `cesr`:
# cesr = { package = "cesr-rs", version = "0.1", features = ["keri", "serder"] }

use cesr::core::matter::matter::Matter; // import name is always `cesr`

Or pin a git tag directly:

[dependencies]
cesr-rs = { git = "https://github.com/devrandom-labs/cesr", tag = "v0.1.0", features = ["keri", "serder"] }

no_std / WASM

The crate builds on wasm32-unknown-unknown and bare-metal no_std targets. Disable default features and select the modules you need plus alloc:

cesr = { git = "https://github.com/devrandom-labs/cesr", tag = "v0.1.0", default-features = false, features = ["alloc", "core", "keri"] }

Building

nix flake check is the single gate (clippy, fmt, taplo, audit, deny, nextest, doctest, wasm32, no_std). Use nix develop to enter the dev shell.
