Expand description

Trait for seekable stream ciphers.

Methods of this trait are generic over the SeekNum trait, which is implemented for primitive numeric types, i.e.: i/u8, i/u16, i/u32, i/u64, i/u128, and i/usize.

Required Methods§

source

fn try_current_pos<T>(&self) -> Result<T, OverflowError>
where T: SeekNum,

Try to get current keystream position

Returns LoopError if position can not be represented by type T

source

fn try_seek<T>(&mut self, pos: T) -> Result<(), LoopError>
where T: SeekNum,

Try to seek to the given position

Returns LoopError if provided position value is bigger than keystream leangth

Provided Methods§

source

fn current_pos<T>(&self) -> T
where T: SeekNum,

Get current keystream position

§Panics

If position can not be represented by type T

source

fn seek<T>(&mut self, pos: T)
where T: SeekNum,

Seek to the given position

§Panics

If provided position value is bigger than keystream leangth

Object Safety§

This trait is not object safe.
