Description

Saltine type classes

Synopsis

Documentation

class IsEncoding a where Source #

Class for all keys and nonces in Saltine which have a representation as ByteString. encoded is a Prism of type Prism' ByteString a compatible with Control.Lens and is automatically deduced.

Minimal complete definition

encode, decode

Methods

encode :: a -> ByteString Source #

decode :: ByteString -> Maybe a Source #

encoded :: (Choice p, Applicative f) => p a (f a) -> p ByteString (f ByteString) Source #

class IsNonce n where Source #

A generic class for interacting with nonces.

Minimal complete definition

zero, nudge

Methods

zero :: n Source #

Some privileged nonce value.

nudge :: n -> n Source #

Some perturbation on nonces such that n /= nudge n with high probability. Since nonces are finite, repeats may happen in particularly small cases, but no nonces in Saltine are so small. This is not guaranteed to be difficult to predict---if a nonce had an Enum instance succ would be a good implementation excepting that succ is partial.
