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 SyntaxContexts, so serialize in a loop until we reach a fixed point.

serialized_expns: Lock<FxHashSet<ExpnId>>latest_expns: Lock<FxHashSet<ExpnId>>

Implementations

Record the fact that we need to serialize the corresponding ExpnData.

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.
