Struct Constraint 

pub struct Constraint<'tcx> {
    pub kind: ConstraintKind,
    pub sub: Region<'tcx>,
    pub sup: Region<'tcx>,
}

Represents a constraint that influences the inference process.

Fields

kind: ConstraintKind

sub: Region<'tcx>

sup: Region<'tcx>

Implementations

impl Constraint<'_>

pub fn involves_placeholders(&self) -> bool

Trait Implementations

impl<'tcx> Clone for Constraint<'tcx>

fn clone(&self) -> Constraint<'tcx>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for Constraint<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> Hash for Constraint<'tcx>

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<'tcx> PartialEq for Constraint<'tcx>

fn eq(&self, other: &Constraint<'tcx>) -> 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.

impl<'tcx> Copy for Constraint<'tcx>

impl<'tcx> Eq for Constraint<'tcx>

impl<'tcx> StructuralPartialEq for Constraint<'tcx>

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.
