Enum PimdirHashAlgo 

pub enum PimdirHashAlgo {
    Blake3,
    Sha256_128,
}

The hash a store names its objects by, as store_meta.hash_algo records it.

Variants

Blake3

BLAKE3, the whole 256-bit digest, which the spec recommends.

Sha256_128

SHA-256 truncated to its first 128 bits, for a consumer whose platform ships SHA-256 and would otherwise bundle a BLAKE3 implementation (the Android app takes this one).

Content addressing needs collision resistance, not signature strength, and a 26-character name keeps the blob paths short.

Implementations

impl PimdirHashAlgo

pub fn as_str(&self) -> &'static str

The spelling store_meta.hash_algo carries.

pub fn parse(algo: &str) -> Option<Self>

The algorithm a stored spelling names, or None for one this crate does not implement, which a caller reports rather than guessing around.

pub fn hash(&self, bytes: &[u8]) -> ReplicaHash

The content hash of a whole body.

pub fn hasher(&self) -> PimdirHasher

An incremental hasher, for a body streamed into the blob store rather than held whole in memory (spec §14’s byteless StoreObject).
