pub struct InlineConstArgs<'tcx> {
    pub args: GenericArgsRef<'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 ClosureArgs have CS and U as type parameters: inline const can reference lifetimes that are internal to the creating function.

Fields§

§args: GenericArgsRef<'tcx>

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

Implementations§

source§

impl<'tcx> InlineConstArgs<'tcx>

source

pub fn new( tcx: TyCtxt<'tcx>, parts: InlineConstArgsParts<'tcx, Ty<'tcx>> ) -> InlineConstArgs<'tcx>

Construct InlineConstArgs from InlineConstArgsParts.

source

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

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

source

pub fn parent_args(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.
