class CanSegment a where

Class of types that support splitting of from the front a packet containing roughly a certain duration.

Minimal complete definition

splitAfterDuration

Methods

splitAfterDuration :: HasStaticDuration d => proxy d -> a -> Maybe (Segment d a, a)

Try to split the packet into the a part which has at most the given duration and a rest. If not possible, e.g. because the input data is already shorter than the given duration, return Nothing.

Instances

(Storable a, HasDuration (Proxy * a)) => CanSegment (SampleBuffer a)

Methods

splitAfterDuration :: HasStaticDuration StaticTicks d => proxy d -> SampleBuffer a -> Maybe (Segment d (SampleBuffer a), SampleBuffer a)

newtype Segment duration c

A segment is some content with a fixed (type level) duration.

Constructors
