only.Expand description
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.
Required Associated Types§
sourcetype NonceOverhead: ArrayLength<u8>
type NonceOverhead: ArrayLength<u8>
Number of bytes this STREAM primitive requires from the nonce.
Required Associated Constants§
sourceconst COUNTER_INCR: Self::Counter
const COUNTER_INCR: Self::Counter
Value to use when incrementing the STREAM counter (i.e. one)
sourceconst COUNTER_MAX: Self::Counter
const COUNTER_MAX: Self::Counter
Maximum value of the STREAM counter.
