Enum LcnfType 

pub enum LcnfType {
    Erased,
    Var(String),
    Fun(Vec<LcnfType>, Box<LcnfType>),
    Ctor(String, Vec<LcnfType>),
    Object,
    Nat,
    LcnfString,
    Unit,
    Irrelevant,
}

LCNF type representation.

Types in LCNF are simplified compared to kernel types. Proof-irrelevant types and universes are erased.

Variants

Erased

Erased type (proof-irrelevant or computationally irrelevant).

Var(String)

A type variable or named type.

Fun(Vec<LcnfType>, Box<LcnfType>)

Function type: params -> return.

Ctor(String, Vec<LcnfType>)

Constructor/inductive type with type arguments.

Object

Object type (boxed/heap-allocated).

Nat

Natural number type.

LcnfString

String type.

Unit

Unit type (erased value placeholder).

Irrelevant

Irrelevant (computationally meaningless, e.g. proofs).

Trait Implementations

impl Clone for LcnfType

fn clone(&self) -> LcnfType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LcnfType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for LcnfType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for LcnfType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LcnfType

fn eq(&self, other: &LcnfType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
