Expand description
Type used to check whether two ast are the same. This is different from the
operator ==
on ast types as this operator would compare true equality with
ID and span.
Note that some expressions kinds are not considered but could be added.
Fields§
§cx: &'a LateContext<'tcx>
Context used to evaluate constant expressions.
maybe_typeck_results: Option<(&'tcx TypeckResults<'tcx>, &'tcx TypeckResults<'tcx>)>
§allow_side_effects: bool
§expr_fallback: Option<Box<dyn FnMut(&Expr<'_>, &Expr<'_>) -> bool + 'a>>
Implementations§

impl<'a, 'tcx> SpanlessEq<'a, 'tcx>
pub fn new(cx: &'a LateContext<'tcx>) -> Self
sourcepub fn deny_side_effects(self) -> Self
pub fn deny_side_effects(self) -> Self
Consider expressions containing potential side effects as not equal.
pub fn expr_fallback( self, expr_fallback: impl FnMut(&Expr<'_>, &Expr<'_>) -> bool + 'a ) -> Self
sourcepub fn inter_expr(&mut self) -> HirEqInterExpr<'_, 'a, 'tcx>
pub fn inter_expr(&mut self) -> HirEqInterExpr<'_, 'a, 'tcx>
Use this method to wrap comparisons that may involve inter-expression context.
See self.locals

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.
