Struct AssocItemConstraint

pub(crate) struct AssocItemConstraint {
    pub(crate) assoc: PathSegment,
    pub(crate) kind: AssocItemConstraintKind,
}

A constraint on an associated item.

Examples

• the A = Ty and B = Ty in Trait<A = Ty, B = Ty>
• the G<Ty> = Ty in Trait<G<Ty> = Ty>
• the A: Bound in Trait<A: Bound>
• the RetTy in Trait(ArgTy, ArgTy) -> RetTy
• the C = { Ct } in Trait<C = { Ct }> (feature associated_const_equality)
• the f(..): Bound in Trait<f(..): Bound> (feature return_type_notation)

Fields

assoc: PathSegment

kind: AssocItemConstraintKind

Implementations

impl AssocItemConstraint

pub(crate) fn print<'a, 'tcx: 'a>( &'a self, cx: &'a Context<'tcx>, ) -> impl Display + 'a + Captures<'tcx>

Trait Implementations

impl Clone for AssocItemConstraint

fn clone(&self) -> AssocItemConstraint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AssocItemConstraint

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

Formats the value using the given formatter.

impl FromClean<AssocItemConstraint> for AssocItemConstraint

fn from_clean( constraint: AssocItemConstraint, renderer: &JsonRenderer<'_>, ) -> Self

impl Hash for AssocItemConstraint

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 AssocItemConstraint

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
