Trait StreamCipherSeek

pub trait StreamCipherSeek {
    // Required methods
    fn try_current_pos<T>(&self) -> Result<T, OverflowError>
       where T: SeekNum;
    fn try_seek<T>(&mut self, pos: T) -> Result<(), StreamCipherError>
       where T: SeekNum;

    // Provided methods
    fn current_pos<T>(&self) -> T
       where T: SeekNum { ... }
    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.: i32, u32, u64, u128, and usize.

Required Methods

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

where T: SeekNum,

Try to get current keystream position

Returns [OverflowError] if position can not be represented by type T

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

where T: SeekNum,

Try to seek to the given position

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

Provided Methods

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

where T: SeekNum,

Get current keystream position

Panics

If position can not be represented by type T

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

where T: SeekNum,

Seek to the given position

Panics

If provided position value is bigger than keystream length

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

impl<T> StreamCipherSeek for StreamCipherCoreWrapper<T>

where T: StreamCipherSeekCore, <T as BlockSizeUser>::BlockSize: IsLess<UInt<UInt<UInt<UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>, B0>, B0>, B0>>, <<T as BlockSizeUser>::BlockSize as IsLess<UInt<UInt<UInt<UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>, B0>, B0>, B0>>>::Output: NonZero,
