Trait Hash

pub trait Hash: Default {
    type Digest: Digest;

    // Required methods
    fn update<T>(&mut self, data: T)
       where T: AsRef<[u8]>;
    fn reset(&mut self);
    fn digest(&self) -> Self::Digest;

    // Provided method
    fn hash<T>(data: T) -> Self::Digest
       where T: AsRef<[u8]> { ... }
}

A trait for hash objects.

Required Associated Types

type Digest: Digest

The type representing the digest produced by finalizing the hash.

Required Methods

fn update<T>(&mut self, data: T)

where T: AsRef<[u8]>,

Updates the hash state with an input data.

fn reset(&mut self)

Resets the hash state to its initial state.

fn digest(&self) -> Self::Digest

Produces the hash digest.

Provided Methods

fn hash<T>(data: T) -> Self::Digest

where T: AsRef<[u8]>,

Calculates the hash digest of an input data.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
