Prisms

_Inherit :: Prism' StdStream StdStream Source #

A prism into the Inherit structure of a StdStream

_UseHandle :: Prism' StdStream Handle Source #

A prism into the UseHandle structure's Handle for a StdStream

_CreatePipe :: Prism' StdStream StdStream Source #

A prism into the CreatePipe structure of a StdStream

_NoStream :: Prism' StdStream StdStream Source #

A prism into the NoStream structure of a StdStream

Classy Prisms

class IsInherit a where Source #

Class constraint proving a type has a prism into an Inherit structure. In general, this seems redundant, however, this class is a proof on a that a is an Inherit, which is a wonderful thing to prove.
