Struct rustc_borrowck::constraints::OutlivesConstraint

pub struct OutlivesConstraint<'tcx> {
    pub sup: RegionVid,
    pub sub: RegionVid,
    pub locations: Locations,
    pub span: Span,
    pub category: ConstraintCategory<'tcx>,
    pub variance_info: VarianceDiagInfo<TyCtxt<'tcx>>,
    pub from_closure: bool,

Fields

sup: RegionVid

The region SUP must outlive SUB…

sub: RegionVid

Region that must be outlived.

locations: Locations

Where did this constraint arise?

span: Span

The Span associated with the creation of this constraint. This should be used in preference to obtaining the span from locations, since the locations may give a poor span in some cases (e.g. converting a constraint from a promoted).

category: ConstraintCategory<'tcx>

What caused this constraint?

variance_info: VarianceDiagInfo<TyCtxt<'tcx>>

Variance diagnostic information

from_closure: bool

If this constraint is promoted from closure requirements.

Trait Implementations

impl<'tcx> Clone for OutlivesConstraint<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for OutlivesConstraint<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> PartialEq for OutlivesConstraint<'tcx>

fn eq(&self, other: &OutlivesConstraint<'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.

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.
