Struct rustc_data_structures::unord::UnordBag
source · pub struct UnordBag<V> {
inner: Vec<V>,
}
Expand description
This is a collection type that tries very hard to not expose any internal iteration. This is a useful property when trying to uphold the determinism invariants imposed by the query system.
This collection type is a good choice for collections the
keys of which don’t have a semantic ordering and don’t implement
Hash
or Eq
.
See MCP 533 for more information.

fn extend_unord<I>(&mut self, items: UnordItems<T, I>)where

Extend this unord collection with the given
UnordItems
.
This method is called extend_unord
instead of just extend
so it
does not conflict with Extend::extend
. Otherwise there would be many
places where the two methods would have to be explicitly disambiguated
via UFCS.source§impl<T> Instrument for T

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
