Struct rustc_span::hygiene::HygieneEncodeContext
source · pub struct HygieneEncodeContext {

latest_expns: Lock<FxHashSet<ExpnId>>,
}
Fields
serialized_ctxts: Lock<FxHashSet<SyntaxContext>>
All SyntaxContexts
for which we have written SyntaxContextData
into crate metadata.
This is None
after we finish encoding SyntaxContexts
, to ensure
that we don’t accidentally try to encode any more SyntaxContexts
latest_ctxts: Lock<FxHashSet<SyntaxContext>>
The SyntaxContexts
that we have serialized (e.g. as a result of encoding Spans
)
in the most recent ‘round’ of serializing. Serializing SyntaxContextData
may cause us to serialize more SyntaxContext
s, so serialize in a loop
until we reach a fixed point.

Implementations
sourceimpl HygieneEncodeContext
impl HygieneEncodeContext
sourcepub fn schedule_expn_data_for_encoding(&self, expn: ExpnId)
pub fn schedule_expn_data_for_encoding(&self, expn: ExpnId)
Record the fact that we need to serialize the corresponding ExpnData
.

&self,
encoder: &mut T,
encode_ctxt: impl FnMut(&mut T, u32, &SyntaxContextData),
encode_expn: impl FnMut(&mut T, ExpnId, &ExpnData, ExpnHash)

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
