Implementations

impl<'tcx> Scopes<'tcx>

pub(crate) fn new() -> Self

fn push_scope( &mut self, region_scope: (Scope, SourceInfo), vis_scope: SourceScope, )

fn pop_scope(&mut self, region_scope: (Scope, SourceInfo)) -> Scope

fn scope_index(&self, region_scope: Scope, span: Span) -> usize

fn topmost(&self) -> Scope

Returns the topmost active scope, which is known to be alive until the next scope expression.

Trait Implementations

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.
