Expand description

Trait for returning digest result with the varaible size

Required Methods§

Source

fn new(output_size: usize) -> Result<Self, InvalidLength>

Create new hasher instance with given output size. Will return Err(InvalidLength) in case if hasher can not work with the given output size. Will always return an error if output size equals to zero.

Source

fn output_size(&self) -> usize

Get output size of the hasher instance provided to the new method

Source

fn variable_result(self, buffer: &mut [u8]) -> Result<&[u8], InvalidLength>

Retrieve the digest result into provided buffer. Length of the buffer must be equal to output size provided to the new method, otherwise Err(InvalidLength) will be returned

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.
