Struct ShaDigest

pub struct ShaDigest<'d, A, S: Borrow<Sha<'d>>> { /* private fields */ }

Available on crate feature unstable only.

An active digest

This implementation might fail after u32::MAX/8 bytes, to increase please see ::finish() length/self.cursor usage

Implementations

impl<'d, A: ShaAlgorithm, S: Borrow<Sha<'d>>> ShaDigest<'d, A, S>

pub fn new(sha: S) -> Self

Creates a new digest

pub fn is_busy(&self) -> bool

Returns true if the hardware is processing the next message.

pub fn update<'a>(&mut self, incoming: &'a [u8]) -> Result<&'a [u8], Infallible>

Updates the SHA digest with the provided data buffer.

pub fn finish(&mut self, output: &mut [u8]) -> Result<(), Infallible>

Finish of the calculation (if not already) and copy result to output After finish() is called update()s will contribute to a new hash which can be calculated again with finish().

Typically, output is expected to be the size of ShaAlgorithm::DIGEST_LENGTH, but smaller inputs can be given to get a “short hash”

pub fn cancel(self) -> S

Discard the current digest and return the peripheral.

Trait Implementations

impl<'d, A: ShaAlgorithm, S: Borrow<Sha<'d>>> FixedOutput for ShaDigest<'d, A, S>

fn finalize_into(self, out: &mut Output<Self>)

Consume value and write result into provided array.

fn finalize_fixed(self) -> GenericArray<u8, Self::OutputSize>

Retrieve result and consume the hasher instance.

impl<'d, A: ShaAlgorithm, S: Borrow<Sha<'d>>> OutputSizeUser for ShaDigest<'d, A, S>

type OutputSize = <A as ShaAlgorithm>::DigestOutputSize

Size of the output in bytes.

fn output_size() -> usize

Return output size in bytes.

impl<'d, A: ShaAlgorithm, S: Borrow<Sha<'d>>> Update for ShaDigest<'d, A, S>

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

Update state using the provided data.

fn chain(self, data: impl AsRef<[u8]>) -> Self

where Self: Sized,

Digest input data in a chained manner.

impl<'d, A: ShaAlgorithm, S: Borrow<Sha<'d>>> HashMarker for ShaDigest<'d, A, S>

implement digest traits if digest feature is present. Note: digest has a blanket trait implementation for digest::Digest for any element that implements FixedOutput + Default + Update + HashMarker
