This is supported on crate feature stream only.

Low-level STREAM implementation.

This trait provides a particular "flavor" of STREAM, as there are different ways the specifics of the construction can be implemented.

Deliberately immutable and stateless to permit parallel operation.

Associated Types

type NonceOverhead: ArrayLength<u8>[src]
