Trait for extendable output functions

Required Methods§

Source

fn new() -> Self

Creates a new instance of the XOF

Source

fn update(&mut self, data: &[u8]) -> Result<()>

Updates the XOF state with new data

Source

fn finalize(&mut self) -> Result<()>

Finalizes the XOF state for output

Source

fn squeeze(&mut self, output: &mut [u8]) -> Result<()>

Squeezes output bytes into the provided buffer

Source

fn squeeze_into_vec(&mut self, len: usize) -> Result<ZeroizingBytes>

Squeezes the specified number of output bytes into exact-size storage that clears itself on drop.

Source

fn reset(&mut self) -> Result<()>

Resets the XOF state

Source

fn security_level() -> usize

Returns the security level in bits

Provided Methods§

Source

fn generate(data: &[u8], len: usize) -> Result<ZeroizingBytes>
where Self: Sized,

Convenience method to generate output in a single call

Dyn Compatibility§

This trait is not dyn compatible.

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