Struct shaman::cryptoutil::FixedBuffer64

pub struct FixedBuffer64 { /* fields omitted */ }

A fixed size buffer of 64 bytes useful for cryptographic operations.

Methods

impl FixedBuffer64

fn new() -> FixedBuffer64

Create a new buffer

Trait Implementations

impl Copy for FixedBuffer64

impl Clone for FixedBuffer64

fn clone(&self) -> FixedBuffer64

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl FixedBuffer for FixedBuffer64

fn input<F: FnMut(&[u8])>(&mut self, input: &[u8], func: F)

Input a vector of bytes. If the buffer becomes full, process it with the provided function and then clear the buffer.

fn reset(&mut self)

Reset the buffer.

fn zero_until(&mut self, idx: usize)

Zero the buffer up until the specified index. The buffer position currently must not be greater than that index.

fn next<'s>(&'s mut self, len: usize) -> &'s mut [u8]

Get a slice of the buffer of the specified size. There must be at least that many bytes remaining in the buffer.

fn full_buffer<'s>(&'s mut self) -> &'s [u8]

Get the current buffer. The buffer must already be full. This clears the buffer as well.

fn current_buffer<'s>(&'s mut self) -> &'s [u8]

Get the current buffer.

fn position(&self) -> usize

Get the current position of the buffer.

fn remaining(&self) -> usize

Get the number of bytes remaining in the buffer until it is full.

fn size(&self) -> usize

Get the size of the buffer
