Struct rustc_trait_selection::traits::const_evaluatable::AbstractConst[−][src]

pub struct AbstractConst<'tcx> {
    pub inner: &'tcx [Node<'tcx>],
    pub substs: SubstsRef<'tcx>,
}
Expand description

A tree representing an anonymous constant.

This is only able to represent a subset of MIR, and should not leak any information about desugarings.

Fields

inner: &'tcx [Node<'tcx>]substs: SubstsRef<'tcx>
