Struct rustc_query_system::query::QuerySideEffects

pub struct QuerySideEffects {
    pub(crate) diagnostics: ThinVec<Diagnostic>,
}

Tracks ‘side effects’ for a particular query. This struct is saved to disk along with the query result, and loaded from disk if we mark the query as green. This allows us to ‘replay’ changes to global state that would otherwise only occur if we actually executed the query method.

Fields

diagnostics: ThinVec<Diagnostic>

Stores any diagnostics emitted during query execution. These diagnostics will be re-emitted if we mark the query as green.

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.
