Struct LinkCollection 

pub(super) struct LinkCollection {
    visited: FxHashMap<ResolutionInfo, Option<(Res, Option<UrlFragment>)>>,
    ambiguous: FxIndexMap<(ItemId, String), Vec<AmbiguousLinks>>,
}

Fields

visited: FxHashMap<ResolutionInfo, Option<(Res, Option<UrlFragment>)>>

Cache the resolved links so we can avoid resolving (and emitting errors for) the same link. The link will be None if it could not be resolved (i.e. the error was cached).

ambiguous: FxIndexMap<(ItemId, String), Vec<AmbiguousLinks>>

According to rustc_resolve, these links are ambiguous.

However, we cannot link to an item that has been stripped from the documentation. If all but one of the “possibilities” are stripped, then there is no real ambiguity. To determine if an ambiguity is real, we delay resolving them until after Cache::populate, then filter every item that doesn’t have a cached path.

We could get correct results by simply delaying everything. This would have fewer happy codepaths, but we want to distinguish different kinds of error conditions, and this is easy to do by resolving links as soon as possible.

Trait Implementations

impl Default for LinkCollection

fn default() -> LinkCollection

Returns the “default value” for a type.

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.
