Struct Sha256 

pub struct Sha256 { /* private fields */ }

SHA-256 over a payload delivered in pieces.

The proxied write path folds this over the request body as it forwards it to object storage, so a reference’s trusted whole-file digest exists without the payload ever being held whole. Pieces must be fed in order.

Implementations

Starts an empty digest.

pub fn update(&mut self, bytes: &[u8])

Folds the next piece of the payload in, in order.

pub fn finish(self) -> StorageChecksum

Closes the digest over everything fed so far.
