Enum rustc_middle::traits::specialization_graph::Node
source · Expand description
A node in the specialization graph is either an impl or a trait definition; either can serve as a source of item definitions. There is always exactly one trait definition node: the root.

Implementations
sourceimpl Node
impl Node
pub fn is_from_trait(&self) -> bool
sourcepub fn item<'tcx>(
&self,
tcx: TyCtxt<'tcx>,
trait_item_def_id: DefId
) -> Option<&'tcx AssocItem>
pub fn item<'tcx>(
&self,
tcx: TyCtxt<'tcx>,
trait_item_def_id: DefId
) -> Option<&'tcx AssocItem>
Tries to find the associated item that implements trait_item_def_id
defined in this node.
If this returns None
, the item can potentially still be found in
parents of this node.

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.
