Struct rustc_interface::queries::Query

pub struct Query<T> {
    result: RefCell<Option<Result<Steal<T>>>>,
}

Represent the result of a query.

This result can be stolen once with the steal method and generated with the compute method.

Fields

result: RefCell<Option<Result<Steal<T>>>>

None means no value has been computed yet.

Implementations

impl<T> Query<T>

fn compute<F: FnOnce() -> Result<T>>(&self, f: F) -> Result<QueryResult<'_, T>>

Trait Implementations

impl<T> Default for Query<T>

fn default() -> Self

Returns the “default value” for a type.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
