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

Represent the result of a query.

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

Fields

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

Implementations

Takes ownership of the query result. Further attempts to take or peek the query result will panic unless it is generated by calling the compute method.

Borrows the query result using the RefCell. Panics if the result is stolen.

Mutably borrows the query result using the RefCell. Panics if the result is stolen.

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

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.
