pub struct AssocItems<'tcx> {
    pub(super) items: SortedIndexMultiMap<u32, Symbol, &'tcx AssocItem>,
}
Expand description

A list of ty::AssocItems in definition order that allows for efficient lookup by name.

When doing lookup by name, we try to postpone hygienic comparison for as long as possible since it is relatively expensive. Instead, items are indexed by Symbol and hygienic comparison is done only on items with the same name.

Fields

items: SortedIndexMultiMap<u32, Symbol, &'tcx AssocItem>

Implementations

Constructs an AssociatedItems map from a series of ty::AssocItems in definition order.

Returns a slice of associated items in the order they were defined.

New code should avoid relying on definition order. If you need a particular associated item for a known trait, make that trait a lang item instead of indexing this array.

Returns an iterator over all associated items with the given name, ignoring hygiene.

Returns the associated item with the given name and AssocKind, if one exists.

Returns the associated item with the given name and any of AssocKind, if one exists.

Returns the associated item with the given name in the given Namespace, if one exists.

Mutably borrows from an owned value. Read more

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous). Read more

This method tries to recover the query key from the given DepNode, something which is needed when forcing DepNodes during red-green evaluation. The query system will only call this method if fingerprint_style() is not FingerprintStyle::Opaque. It is always valid to return None here, in which case incremental compilation will treat the query as having changed instead of forcing it. Read more

Returns the argument unchanged.

Calls U::from(self).

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

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.
