pub struct Context { /* private fields */ }
Expand description
A context for multi-step (Init-Update-Finish) digest calculations.
use ring::digest;
let one_shot = digest::digest(&digest::SHA384, b"hello, world");
let mut ctx = digest::Context::new(&digest::SHA384);
ctx.update(b"hello");
ctx.update(b", ");
ctx.update(b"world");
let multi_part = ctx.finish();
assert_eq!(&one_shot.as_ref(), &multi_part.as_ref());
Constructs a new context.
Updates the digest with all the data in data
.
Finalizes the digest calculation and returns the digest value.
finish
consumes the context so it cannot be (mis-)used after finish
has been called.
The algorithm that this context is using.
Performs copy-assignment from
source
.

Returns the argument unchanged.
Calls U::from(self)

That is, this conversion is whatever the implementation of
From<T> for U
chooses to do.
