FRP.Rhine.ResamplingBuffer

This module introduces ResamplingBuffers, which are primitives that consume and produce data at different rates. Just as schedules form the boundaries between different clocks, (resampling) buffers form the boundaries between synchronous signal functions ticking at different speeds.

Documentation

type ResBuf m cla clb a b = ResamplingBuffer m cla clb a b

A type synonym to allow for abbreviation.

data ResamplingBuffer m cla clb a b

A stateful buffer from which one may get a value, or to which one may put a value, depending on the clocks. ResamplingBuffers can be clock-polymorphic, or specific to certain clocks.

• m: Monad in which the ResamplingBuffer may have side effects
• cla: The clock at which data enters the buffer
• clb: The clock at which data leaves the buffer
• a: The input type
• b: The output type

Constructors

ResamplingBuffer

Fields

• put :: TimeInfo cla -> a -> m (ResamplingBuffer m cla clb a b)

  Store one input value of type a at a given time stamp, and return a continuation.

• get :: TimeInfo clb -> m (b, ResamplingBuffer m cla clb a b)

  Retrieve one output value of type b at a given time stamp, and a continuation.

hoistResamplingBuffer :: (Monad m1, Monad m2) => (forall c. m1 c -> m2 c) -> ResamplingBuffer m1 cla clb a b -> ResamplingBuffer m2 cla clb a b

Hoist a ResamplingBuffer along a monad morphism.
