Struct cipher::StreamCipherCoreWrapper

pub struct StreamCipherCoreWrapper<T: BlockSizeUser>
where
    T::BlockSize: IsLess<U256>,
    Le<T::BlockSize, U256>: NonZero,
{ /* private fields */ }

Wrapper around StreamCipherCore implementations.

It handles data buffering and implements the slice-based traits.
