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
T: SeekNum, { ... } pub fn seek<T>(&mut self, pos: T)
where
T: SeekNum, { ... } }
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]
T: SeekNum,
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]
T: SeekNum,
Try to seek to the given position
Returns LoopError
if provided position value is bigger than
keystream length.
Provided methods
pub fn current_pos<T>(&self) -> T where
T: SeekNum,
[src]
T: SeekNum,
pub fn seek<T>(&mut self, pos: T) where
T: SeekNum,
[src]
T: SeekNum,
