Trait StreamingMac 

pub trait StreamingMac: Send {
    // Required methods
    fn update(&mut self, data: &[u8]);
    fn finalize(self, out: &mut [u8]) -> Result<(), CryptoError>;
    fn verify(self, expected: &[u8]) -> Result<(), CryptoError>;
}

Incremental (streaming) MAC computation.

Required Methods

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

Feed additional data into the MAC state.

fn finalize(self, out: &mut [u8]) -> Result<(), CryptoError>

Consume the MAC state and write the tag into out.

fn verify(self, expected: &[u8]) -> Result<(), CryptoError>

Consume the MAC state, compute the tag, and verify against expected in constant time.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
