[−][src]Struct rustc_ap_rustc_session::parse::GatedSpans
Collected spans during parsing for places where a certain feature was
used and should be feature gated accordingly in check_crate
.
Fields
spans: Lock<FxHashMap<Symbol, Vec<Span>>>
Methods
impl GatedSpans
[src]
pub fn gate(&self, feature: Symbol, span: Span)
[src]
Feature gate the given span
under the given feature
which is same Symbol
used in active.rs
.
pub fn ungate_last(&self, feature: Symbol, span: Span)
[src]
Ungate the last span under the given feature
.
Panics if the given span
wasn't the last one.
Using this is discouraged unless you have a really good reason to.
pub fn is_ungated(&self, feature: Symbol) -> bool
[src]
Is the provided feature
gate ungated currently?
Using this is discouraged unless you have a really good reason to.
pub fn merge(&self, spans: FxHashMap<Symbol, Vec<Span>>)
[src]
Prepend the given set of spans
onto the set in self
.
