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.: i32, u32, u64, u128, and usize.

Required Methods§

source

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

Try to get current keystream position

Returns OverflowError if position can not be represented by type T

source

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

Try to seek to the given position

Returns StreamCipherError if provided position value is bigger than keystream length.

Provided Methods§

source

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

Get current keystream position

§Panics

If position can not be represented by type T

source

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

Seek to the given position

§Panics

If provided position value is bigger than keystream length

Object Safety§

This trait is not object safe.
