Struct AxiomBody 

pub struct AxiomBody {
    pub expr: Expr,
    pub patterns: List<Expr>,
}

Fields

expr: Expr

patterns: List<Expr>

The terms used as the pattern (trigger) to instantiate the axiom: each application of an uninterpreted function occurring in expr. See Axiom::new.

Trait Implementations

impl Debug for AxiomBody

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

Formats the value using the given formatter.

impl TypeFoldable for AxiomBody

fn try_fold_with<__F: FallibleTypeFolder>( &self, __folder: &mut __F, ) -> Result<Self, __F::Error>

fn fold_with<F: TypeFolder>(&self, folder: &mut F) -> Self

fn reduce(&self, genv: GlobalEnv<'_, '_>) -> Self

Reduces expressions by

fn replace_holes( &self, f: impl FnMut(&[BoundVariableKinds], HoleKind) -> Expr, ) -> Self

Replaces all holes with the result of calling a closure. The closure takes a list with all the layers of bound variables at the point the hole was found. Each layer corresponds to the list of bound variables at that level. The list is ordered from outermost to innermost binder, i.e., the last element is the binder closest to the hole.

fn with_holes(&self) -> Self

Remove all refinements and turn each underlying BaseTy into a TyKind::Exists with a TyKind::Constr and a hole. For example, Vec<{v. i32[v] | v > 0}>[n] becomes {n. Vec<{v. i32[v] | *}>[n] | *}.

fn replace_evars( &self, f: &mut impl FnMut(EVid) -> Option<Expr>, ) -> Result<Self, EVid>

fn shift_horizontally(&self, amount: usize) -> Self

Shift the BoundVar of all the the variables at index INNERMOST “horizontally” to the right by the specified amount.

fn shift_in_escaping(&self, amount: u32) -> Self

fn shift_out_escaping(&self, amount: u32) -> Self

fn erase_regions(&self) -> Self

fn erase_regions_including_bound(&self) -> Self

Like TypeFoldable::erase_regions, but also erases bound regions.

impl TypeVisitable for AxiomBody

fn visit_with<__V: TypeVisitor>( &self, __visitor: &mut __V, ) -> ControlFlow<__V::BreakTy>

fn has_escaping_bvars(&self) -> bool

fn has_escaping_bvars_at_or_above(&self, binder: DebruijnIndex) -> bool

Returns true if self has any late-bound vars that are either bound by binder or bound by some binder outside of binder. If binder is ty::INNERMOST, this indicates whether there are any late-bound vars that appear free.

fn fvars(&self) -> FxHashSet<Name>

Returns the set of all free variables. For example, Vec<i32[n]>{v : v > m} returns {n, m}.

fn early_params(&self) -> FxHashSet<EarlyReftParam>

fn redundant_bvars(&self) -> UnordSet<BoundVar>

Gives the indices of the provided bvars which:
