    pub types: TypeSubst,
    pub rows: RowSubst,
}

Combined substitution environment

Fields

rows: RowSubst

Implementations

impl Subst

pub fn empty() -> Self

Create an empty substitution

pub fn apply_type(&self, ty: &Type) -> Type

Apply substitutions to a Type

pub fn apply_stack(&self, stack: &StackType) -> StackType

Apply substitutions to a StackType

pub fn compose(&self, other: &Subst) -> Subst

Compose two substitutions (apply other after self) Result: (other ∘ self) where self is applied first, then other

Trait Implementations

impl Clone for Subst

fn clone(&self) -> Subst

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Subst

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

Formats the value using the given formatter.

impl PartialEq for Subst

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