Trait gost_modes::StreamCipherSeek[−][src]

pub trait StreamCipherSeek {
    pub fn try_current_pos<T>(&self) -> Result<T, OverflowError>
    where
        T: SeekNum;

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

    pub fn current_pos<T>(&self) -> T
    where

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

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

Try to get current keystream position

Returns LoopError if position can not be represented by type T

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

Try to seek to the given position

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