Generalized RoMix interface with a runtime R value

Required Methods§

Source

fn ro_mix_front_ex<S: Salsa20<Lanes = U1>>( &mut self, r: NonZeroU32, cf: NonZeroU8, )

Perform the front part of the $RoMix$ operation

Buffer must be at least 128 * r * (n + 1) bytes long.

Source

fn ro_mix_back_ex<S: Salsa20<Lanes = U1>>( &mut self, r: NonZeroU32, cf: NonZeroU8, ) -> &[u8] ⓘ

Perform the back part of the $RoMix$ operation

Buffer must be at least 128 * r * (n + 2) bytes long.

Return: the raw salt output for the completed $RoMix$ operation

Source

fn ro_mix_interleaved_ex<'a, S: Salsa20<Lanes = U2>>( &'a mut self, front: &mut Self, r: NonZeroU32, cf: NonZeroU8, ) -> &'a [u8] ⓘ

Interleave the front and back parts of the $RoMix$ operation in two independent buffers

Buffer must be at least 128 * r * (n + 2) bytes long.

Return: the raw salt output for the completed $RoMix$ operation

Source

fn ro_mix_input_buffer(&mut self, r: NonZeroU32) -> &mut [u8] ⓘ

Convenience method to get the input buffer for the $RoMix$ operation

Always return the 128 * r bytes of the buffer

Provided Methods§

Source

fn ro_mix_front(&mut self, r: NonZeroU32, cf: NonZeroU8)

Perform the front part of the $RoMix$ operation

Buffer must be at least 128 * r * (n + 1) bytes long.

Source

fn ro_mix_back(&mut self, r: NonZeroU32, cf: NonZeroU8) -> &[u8] ⓘ

Perform the back part of the $RoMix$ operation

Buffer must be at least 128 * r * (n + 2) bytes long.

Return: the raw salt output for the completed $RoMix$ operation

Source

fn ro_mix_interleaved( &mut self, front: &mut Self, r: NonZeroU32, cf: NonZeroU8, ) -> &[u8] ⓘ

Interleave the front and back parts of the $RoMix$ operation in two independent buffers

Buffer must be at least 128 * r * (n + 2) bytes long.

Return: the raw salt output for the completed $RoMix$ operation

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.
