Covenant.Type

Description

Covenant's type system and various ways to construct types.

Since: 1.0.0

Synopsis

Type abstractions

data AbstractTy Source #

A type abstraction, using a combination of a DeBruijn index (to indicate which scope it refers to) and a positional index (to indicate which bound variable in that scope it refers to).

Important note

This is a relative representation: any given AbstractTy could refer to different things when placed in different positions in the ASG. This stems from how DeBruijn indices behave: Z refers to 'our immediate enclosing scope', S Z to 'one scope outside our immediate enclosing scope', etc. This can mean different things depending on what these scope(s) are.

Since: 1.0.0

Constructors

BoundAt DeBruijn (Index "tyvar")

data Renamed Source #

A type abstraction that has undergone renaming from a specific context.

Since: 1.0.0

Constructors

Rigid Int (Index "tyvar")

Set by an enclosing scope, and thus is essentially a concrete type, we just don't know which. First field is its 'true level', second field is the positional index in that scope.

Unifiable (Index "tyvar")

Can be unified with something, but must be consistent: that is, only one unification for every instance. Field is this variable's positional index; we don't need to track the scope, as only one scope contains unifiable bindings.

Wildcard Word64 Int (Index "tyvar")

Must unify with everything, except with other distinct wildcards in the same scope. First field is a unique scope identifier; second is its 'true level' simialr to Rigid; third is the positional index within its scope. We must have unique identifiers for wildcard scopes, as wildcards unify with everything except other wildcards in the same scope, and child scopes aren't unique.

Computation types

data CompT a where Source #

A computation type, with abstractions indicated by the type argument. In pretty much any case imaginable, this would be either AbstractTy (in the ASG), or Renamed (after renaming).

Since: 1.0.0

Bundled Patterns

pattern Comp0 :: CompTBody a -> CompT a

A computation type that does not bind any type variables. Use this like a data constructor.

Since: 1.0.0

pattern Comp1 :: CompTBody a -> CompT a

A computation type that binds one type variable (that is, something whose type is forall a . ... -> ...). Use this like a data constructor.

Since: 1.0.0

pattern Comp2 :: CompTBody a -> CompT a

A computation type that binds two type variables (that is, something whose type is forall a b . ... -> ...). Use this like a data constructor.

Since: 1.0.0

pattern Comp3 :: CompTBody a -> CompT a

A computation type that binds three type variables (that is, something whose type is forall a b c . ... -> ...). Use this like a data constructor.

Since: 1.0.0

pattern CompN :: Count "tyvar" -> CompTBody AbstractTy -> CompT AbstractTy

A general way to construct and deconstruct computations which bind an arbitrary number of type variables. Use this like a data constructor. Unlike the other Comp patterns, CompN is exhaustive if matched on.

Methods

data CompTBody a where Source #

The 'body' of a computation type, consisting of the types of its arguments and the type of its result.

Since: 1.0.0

Bundled Patterns

pattern ReturnT :: ValT a -> CompTBody a

The body of a computation type that doesn't take any arguments and produces the a result of the given value type. Use this just as you would a data constructor.

Example

Since: 1.0.0

pattern (:--:>) :: ValT a -> CompTBody a -> CompTBody a infixr 1

Given a type of argument, and the body of another computation type, construct a copy of the body, adding an extra argument of the argument type. Use this just as you would a data constructor.

Note

Together with ReturnT, these two patterns provide an exhaustive pattern match.

Example

Since: 1.0.0

pattern ArgsAndResult :: Vector (ValT a) -> ValT a -> CompTBody a

A view of a computation type as a Vector of its argument types, together with its result type. Can be used as a data constructor, and is an exhaustive match.
