Struct StreamingHasher 

pub struct StreamingHasher { /* private fields */ }

Incremental hasher that computes MD5 and optionally additional checksums over a stream of data chunks.

Examples

use rustack_s3_core::checksums::{ChecksumAlgorithm, StreamingHasher};

let mut hasher = StreamingHasher::new(&[ChecksumAlgorithm::Sha256]);
hasher.update(b"hello ");
hasher.update(b"world");
let result = hasher.finish();
assert!(!result.md5_hex.is_empty());
assert_eq!(result.checksums.len(), 1);

Implementations

impl StreamingHasher

pub fn new(algorithms: &[ChecksumAlgorithm]) -> Self

Create a new streaming hasher.

MD5 is always computed. Provide additional algorithms in algorithms to compute extra checksums.

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

Feed more data into the hasher.

pub fn finish(self) -> HasherResult

Finalize the hasher and return the results.

This consumes the hasher.

Trait Implementations

impl Debug for StreamingHasher

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
