}

Named reduction rules for tracing.

Variants

Beta

Beta reduction: (λx.body) arg → body[arg/x].

Delta

Delta reduction: unfold a definition.

Zeta

Zeta reduction: let x := v in body → body[v/x].

Iota

Iota reduction: recursor application.

Proj

Projection reduction.

Quot

Quotient reduction.

NatLit

Nat literal operation.

StrLit

String literal operation.

None

No reduction was possible.

Trait Implementations

impl Clone for ReductionRule

fn clone(&self) -> ReductionRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReductionRule

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

Formats the value using the given formatter.

impl Display for ReductionRule

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

Formats the value using the given formatter.

impl PartialEq for ReductionRule

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