pub struct InlineConstSubsts<'tcx> {
    pub substs: SubstsRef<'tcx>,
}
Expand description

An inline const is modeled like

const InlineConst<'l0...'li, T0...Tj, R>: R;

where:

  • ’l0…’li and T0…Tj are the generic parameters inherited from the item that defined the inline const,
  • R represents the type of the constant.

When the inline const is instantiated, R is substituted as the actual inferred type of the constant. The reason that R is represented as an extra type parameter is the same reason that ClosureSubsts have CS and U as type parameters: inline const can reference lifetimes that are internal to the creating function.

Fields§

§substs: SubstsRef<'tcx>

Generic parameters from the enclosing item, concatenated with the inferred type of the constant.

Implementations§

source§

impl<'tcx> InlineConstSubsts<'tcx>

source

pub fn new( tcx: TyCtxt<'tcx>, parts: InlineConstSubstsParts<'tcx, Ty<'tcx>> ) -> InlineConstSubsts<'tcx>

Construct InlineConstSubsts from InlineConstSubstsParts.

source

fn split(self) -> InlineConstSubstsParts<'tcx, GenericArg<'tcx>>

Divides the inline const substs into their respective components. The ordering assumed here must match that used by InlineConstSubsts::new above.

source

pub fn parent_substs(self) -> &'tcx [GenericArg<'tcx>]

Returns the substitutions of the inline const’s parent.

source

pub fn ty(self) -> Ty<'tcx>

Returns the type of this inline const.

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.
