Context

rama::crypto::dep::aws_lc_rs::digest

Struct Context 

pub struct Context { /* private fields */ }
Expand description

A context for multi-step (Init-Update-Finish) digest calculations.

Implementations§

§

impl Context

pub fn new(algorithm: &'static Algorithm) -> Context

Constructs a new context.

§Panics

new panics if it fails to initialize an aws-lc digest context for the given algorithm.

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

Updates the message to digest with all the data in data.

§Panics

Panics if update causes total input length to exceed maximum allowed (u64::MAX).

pub fn finish(self) -> Digest

Finalizes the digest calculation and returns the digest value.

finish consumes the context so it cannot be (mis-)used after finish has been called.

§Panics

Panics if the digest is unable to be finalized

pub fn algorithm(&self) -> &'static Algorithm

The algorithm that this context is using.
