Module flod.traits

This module defines templates for determining characteristics of stream components at compile time.

Templates

Name	Description
`CommonType`	Aliases to the element type can be accepted by both `Source` `and` `Sink` stages. If both can work on any types and do not specify defaults, `CommonType` `aliases to` `DefaultType`.
`DefaultAllocType`
`DefaultPeekType`
`FixedAllocType`
`FixedPeekType`
`FixedPullType`
`FixedPushType`

Name	Type	Description
`areCompatible`		Returns `true` `if` `S[0]` `is a source and` `S[1]` is a sink and they both use the same method of passing data.
`isActiveSink`
`isActiveSource`
`isAllocable`
`isAllocSink`		Returns `true` `if` `S` `is a sink to which data can be written by calling` `alloc()` `and` `commit()`.
`isAllocSource`		Returns `true` `if` `S` `is a source which writes data by calling` `alloc()` `and` `commit()`.
`isPassiveSink`
`isPassiveSource`
`isPeekable`
`isPeekSink`		Returns `true` `if` `S` `is a sink which reads data by calling` `peek()` `and` `consume()`.
`isPeekSource`		Returns `true` `if` `S` `is a source from which data can be read by calling` `peek()` `and` `consume()`.
`isPullable`
`isPullSink`		Returns `true` `if` `S` `is a sink which reads data by calling` `pull()`.
`isPullSource`		Returns `true` `if` `S` `is a source from which data can be read by calling` `pull()`.
`isPushable`
`isPushSink`		Returns `true` `if` `S` `is a sink to which data can be written by calling` `push()`.
`isPushSource`		Returns `true` `if` `S` `is a source which writes data by calling` `push()`.
`isRunnable`
`isSink`		Returns `true` `if` `S` is a sink of any kind.
`isSinkOnly`		Returns `true` `if` `S` is a sink but not a source.
`isSource`		Returns `true` `if` `S` is a source of any kind.
`isSourceOnly`		Returns `true` `if` `S` is a source but not a sink.
`isStage`		Returns `true` `if` `S` is a source or a sink.
