Struct Declaration 

pub struct Declaration {
    pub name: SymbolId,
    pub level_params: Vec<u32>,
    pub ty: TermId,
    pub value: Option<TermId>,
    pub attrs: Attributes,
    pub kind: DeclKind,
}

A constant declaration in the environment

Fields

name: SymbolId

Name of the constant

level_params: Vec<u32>

Universe parameters

ty: TermId

Type of the constant

value: Option<TermId>

Value (body) of the constant (None for axioms)

attrs: Attributes

Attributes

kind: DeclKind

Kind of declaration

Implementations

impl Declaration

pub fn def( name: SymbolId, level_params: Vec<u32>, ty: TermId, value: TermId, ) -> Self

Create a new definition

pub fn axiom(name: SymbolId, level_params: Vec<u32>, ty: TermId) -> Self

Create a new axiom

pub fn theorem( name: SymbolId, level_params: Vec<u32>, ty: TermId, proof: TermId, ) -> Self

Create a new theorem (opaque definition)

pub fn is_reducible(&self) -> bool

Check if this declaration can be unfolded

pub fn is_opaque(&self) -> bool

Check if this declaration is opaque (cannot be unfolded)

Trait Implementations

impl Clone for Declaration

fn clone(&self) -> Declaration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Declaration

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

Formats the value using the given formatter.

impl PartialEq for Declaration

fn eq(&self, other: &Declaration) -> 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.
