Struct ContentHasher 

pub struct ContentHasher(/* private fields */);

An incremental SHA-256 over a blob’s plaintext, so the streaming download path verifies a blob’s content hash without holding the whole plaintext in memory: feed each decrypted chunk to update, call finish, and compare the returned digest with the row’s hash before committing the bytes to the cache. The hex-encoded digest matches content_hash over the same bytes.

Implementations

impl ContentHasher

pub fn new() -> Self

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

Fold the next plaintext chunk into the running digest.

pub fn finish(self) -> String

The lowercase-hex digest of everything fed so far.

Trait Implementations

impl Default for ContentHasher

fn default() -> Self

Returns the “default value” for a type.
