Struct rustc_trait_selection::traits::const_evaluatable::AbstractConst

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

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>

Implementations

impl<'tcx> AbstractConst<'tcx>

pub fn new(
    tcx: TyCtxt<'tcx>,
    uv: Unevaluated<'tcx, ()>
) -> Result<Option<AbstractConst<'tcx>>, ErrorReported>

pub fn from_const(
    tcx: TyCtxt<'tcx>,
    ct: &Const<'tcx>
) -> Result<Option<AbstractConst<'tcx>>, ErrorReported>

pub fn subtree(self, node: NodeId) -> AbstractConst<'tcx>

pub fn root(self) -> Node<'tcx>

Trait Implementations

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for AbstractConst<'tcx>

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

Formats the value using the given formatter.

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.
