A trait for salsa20 block types

Required Associated Types

type Lanes: ArrayLength

The number of lanes

type Block: BlockType

The block type

Required Methods

fn read(ptr: GenericArray<&Self::Block, Self::Lanes>) -> Self

Read block(s)

fn write(&self, ptr: GenericArray<&mut Self::Block, Self::Lanes>)

Write block(s) back

The original/saved value must be present in the pointer.

fn keystream<const ROUND_PAIRS: usize>(&mut self)

Apply the keystream to the block(s)

Provided Methods

fn shuffle_in(_ptr: &mut Align64<[u32; 16]>)

Shuffle data into optimal representation

fn shuffle_out(_ptr: &mut Align64<[u32; 16]>)

Shuffle data out of optimal representation

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.

Implementors
