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

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.
