}

Fields

r: &'b mut Resolver<'a>

parent_scope: ParentScope<'a>

The module that represents the current item scope.

ribs: PerNS<Vec<Rib<'a>>>

The current set of local scopes for types and values. FIXME #4948: Reuse ribs to avoid allocation.

last_block_rib: Option<Rib<'a>>

Previous poped rib, only used for diagnostic.

label_ribs: Vec<Rib<'a, NodeId>>

The current set of local scopes, for labels.

lifetime_ribs: Vec<LifetimeRib>

The current set of local scopes for lifetimes.

lifetime_elision_candidates: Option<Vec<(LifetimeRes, LifetimeElisionCandidate)>>

We are looking for lifetimes in an elision context. The set contains all the resolutions that we encountered so far. They will be used to determine the correct lifetime for the fn return type. The LifetimeElisionCandidate is used for diagnostics, to suggest introducing named lifetimes.

current_trait_ref: Option<(&'a ModuleData<'a>, TraitRef)>

The trait that the current context can refer to.

diagnostic_metadata: Box<DiagnosticMetadata<'ast>>

Fields used to add information to diagnostic errors.

in_func_body: bool

State used to know whether to ignore resolution errors for function bodies.

In particular, rustdoc uses this to avoid giving errors for cfg() items. In most cases this will be None, in which case errors will always be reported. If it is true, then it will be updated when entering a nested function or trait body.

lifetime_uses: FxHashMap<LocalDefId, LifetimeUseSet>

Count the number of places a lifetime is used.

fn binding_mode_map(&mut self, pat: &Pat) -> FxHashMap<Ident, BindingInfo>

fn resolve_pattern_inner(
    &mut self,
    pat: &Pat,
    pat_src: PatternSource,
    bindings: &mut SmallVec<[(PatBoundCtx, FxHashSet<Ident>); 1]>
)

Resolve bindings in a pattern. This is a helper to resolve_pattern.

bindings

A stack of sets of bindings accumulated.

In each set, PatBoundCtx::Product denotes that a found binding in it should be interpreted as re-binding an already bound binding. This results in an error. Meanwhile, PatBound::Or denotes that a found binding in the set should result in reusing this binding rather than creating a fresh one.

When called at the top level, the stack must have a single element with PatBound::Product. Otherwise, pushing to the stack happens as or-patterns (p_0 | ... | p_n) are encountered and the context needs to be switched to PatBoundCtx::Or and then PatBoundCtx::Product for each p_i. When each p_i has been dealt with, the top set is merged with its parent. When a whole or-pattern has been dealt with, the thing happens.

See the implementation and fresh_binding for more details.
