Struct DeclData 

pub(crate) struct DeclData<'ra> {
    pub(crate) kind: DeclKind<'ra>,
    pub(crate) ambiguity: CmCell<Option<Interned<'ra, DeclData<'ra>>>>,
    pub(crate) warn_ambiguity: CmCell<bool>,
    pub(crate) expansion: LocalExpnId,
    pub(crate) span: Span,
    pub(crate) vis: CmCell<Visibility<DefId>>,
    pub(crate) parent_module: Option<Module<'ra>>,
}

Data associated with any name declaration.

Fields

kind: DeclKind<'ra>

ambiguity: CmCell<Option<Interned<'ra, DeclData<'ra>>>>

warn_ambiguity: CmCell<bool>

Produce a warning instead of an error when reporting ambiguities inside this binding. May apply to indirect ambiguities under imports, so ambiguity.is_some() is not required.

expansion: LocalExpnId

span: Span

vis: CmCell<Visibility<DefId>>

parent_module: Option<Module<'ra>>

Implementations

impl<'ra> DeclData<'ra>

pub(crate) fn vis(&self) -> Visibility<DefId>

pub(crate) fn res(&self) -> Res<NodeId>

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

pub(crate) fn descent_to_ambiguity( self: Interned<'ra, DeclData<'ra>>, ) -> Option<(Interned<'ra, DeclData<'ra>>, Interned<'ra, DeclData<'ra>>)>

pub(crate) fn is_ambiguity_recursive(&self) -> bool

pub(crate) fn warn_ambiguity_recursive(&self) -> bool

pub(crate) fn is_possibly_imported_variant(&self) -> bool

pub(crate) fn is_extern_crate(&self) -> bool

pub(crate) fn is_import(&self) -> bool

pub(crate) fn is_import_user_facing(&self) -> bool

The binding introduced by #[macro_export] macro_rules is a public import, but it might not be perceived as such by users, so treat it as a non-import in some diagnostics.

pub(crate) fn is_glob_import(&self) -> bool

pub(crate) fn is_assoc_item(&self) -> bool

pub(crate) fn macro_kinds(&self) -> Option<MacroKinds>

pub(crate) fn reexport_chain( self: Interned<'ra, DeclData<'ra>>, r: &Resolver<'_, '_>, ) -> SmallVec<[Reexport; 2]>

pub(crate) fn may_appear_after( &self, invoc_parent_expansion: LocalExpnId, decl: Interned<'_, DeclData<'_>>, ) -> bool

pub(crate) fn determined(&self) -> bool

Returns whether this declaration may be shadowed or overwritten by something else later. FIXME: this function considers unexpanded_invocations, but not single_imports, so the declaration may not be as “determined” as we think. FIXME: relationship between this function and similar NameResolution::determined_decl is unclear.

Trait Implementations

impl<'ra> Clone for DeclData<'ra>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'ra> Debug for DeclData<'ra>

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

Formats the value using the given formatter.

impl Hash for DeclData<'_>

fn hash<H>(&self, _: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
