Reader and writer traits to generalise over writing to and reading from buffers in memory and cryptographic constructions which take variable length input or generate variable length output.

Structs

Requested a write larger than self.capacity().

Traits

CryptoReader

Marker trait to indicate that the output of a Reader can be considered to be pseudo random.

Reader

An object from which bytes can be read.

Writer

Functions

check_write_size

Helper function checking that requested <= capacity and creating an appropriate WriteTooLargeError if this is not the case.
