Documentation

data Extensibility Source #

Used at the type level to indicate "open" vs "closed" structure.

Constructors

Open	An "open" structure with a unique, unnamed control-flow edge flowing in or out. "Fallthrough" and concatenation are permitted at an open point.
Closed	A "closed" structure which supports control transfer only through the use of named labels---no "fallthrough" is permitted. The number of control-flow edges is unconstrained.

type O = 'Open Source #

type C = 'Closed Source #

data MaybeO (ex :: Extensibility) t where Source #

Maybe type indexed by open/closed

Constructors

JustO :: forall t. t -> MaybeO 'Open t
NothingO :: forall t. MaybeO 'Closed t

data Block (n :: Extensibility -> Extensibility -> Type) (e :: Extensibility) (x :: Extensibility) where Source #

A sequence of nodes. May be any of four shapes (OO, OC, CO, CC). Open at the entry means single entry, mutatis mutandis for exit. A closedclosed block is a basic/ block and can't be extended further. Clients should avoid manipulating blocks and should stick to either nodes or graphs.
