Module blake3 

BLAKE3-native plumbing for [jf_merkle_tree::MerkleTree].

jf_merkle_tree::hasher::GenericHasherMerkleTree<H, ...> requires H: digest::Digest (the RustCrypto trait). The BLAKE3 crate only implements that trait via its traits-preview feature, which is pinned to a specific digest crate version — it lags behind blake3’s release cadence and forces the rest of the workspace onto an old blake3 line.

These helpers let us drive MerkleTree directly with blake3’s native API.

Structs

Blake3DigestAlgorithm
