Struct Hasher 

pub struct Hasher { /* private fields */ }

Streaming hasher for computing document and file hashes.

Implementations

impl Hasher

pub fn new(algorithm: HashAlgorithm) -> Self

Create a new hasher with the specified algorithm.

pub fn default_algorithm() -> Self

Create a new hasher with the default algorithm (SHA-256).

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

Update the hasher with data.

pub fn finalize(self) -> DocumentId

Finalize the hash and return the document ID.

pub fn hash(algorithm: HashAlgorithm, data: &[u8]) -> DocumentId

Hash data in one shot.

pub fn hash_reader<R: Read>( algorithm: HashAlgorithm, reader: &mut R, ) -> Result<DocumentId>

Hash data from a reader.

Errors

Returns an error if reading from the reader fails.
