Struct NameResolution 

pub(crate) struct NameResolution<'ra> {
    pub single_imports: FxIndexSet<Interned<'ra, ImportData<'ra>>>,
    pub non_glob_decl: Option<Interned<'ra, DeclData<'ra>>>,
    pub glob_decl: Option<Interned<'ra, DeclData<'ra>>>,
    pub orig_ident_span: Span,
}

Records information about the resolution of a name in a namespace of a module.

Fields

single_imports: FxIndexSet<Interned<'ra, ImportData<'ra>>>

Single imports that may define the name in the namespace. Imports are arena-allocated, so it’s ok to use pointers as keys.

non_glob_decl: Option<Interned<'ra, DeclData<'ra>>>

The non-glob declaration for this name, if it is known to exist.

glob_decl: Option<Interned<'ra, DeclData<'ra>>>

The glob declaration for this name, if it is known to exist.

orig_ident_span: Span

Implementations

impl<'ra> NameResolution<'ra>

pub(crate) fn new(orig_ident_span: Span) -> Self

pub(crate) fn determined_decl(&self) -> Option<Interned<'ra, DeclData<'ra>>>

Returns the best declaration if it is not going to change, and None if the best declaration may still change to something else. FIXME: this function considers single_imports, but not unexpanded_invocations, so the returned declaration may actually change after expanding macros in the same module, because of this fact we have glob overwriting (select_glob_decl). Consider using unexpanded_invocations here and avoiding glob overwriting entirely, if it doesn’t cause code breakage in practice. FIXME: relationship between this function and similar DeclData::determined is unclear.

pub(crate) fn best_decl(&self) -> Option<Interned<'ra, DeclData<'ra>>>

Trait Implementations

impl<'ra> Clone for NameResolution<'ra>

fn clone(&self) -> NameResolution<'ra>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'ra> Debug for NameResolution<'ra>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
