pub trait Sha256 {
    type Context: Send + Sync + Clone;

    // Required methods
    fn init() -> Self::Context;
    fn update(ctx: &mut Self::Context, data: &[u8]);
    fn finalize(ctx: Self::Context, out: &mut [u8; 32]);
}

type Context: Send + Sync + Clone

Opaque storage for the implementation’s hash state.

Required Methods

fn init() -> Self::Context

Start a new hash computation.

fn update(ctx: &mut Self::Context, data: &[u8])
