pub fn resolved_crate(self, db: &dyn HirDatabase) -> Option<Crate>

pub fn name(self, db: &dyn HirDatabase) -> Name

pub fn alias(self, db: &dyn HirDatabase) -> Option<ImportAlias>

pub fn alias_or_name(self, db: &dyn HirDatabase) -> Option<Name>

Returns the name under which this crate is made accessible, taking _ into account.

Trait Implementations

impl Clone for ExternCrateDecl

fn clone(&self) -> ExternCrateDecl

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExternCrateDecl

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

Formats the value using the given formatter.

impl From<ExternCrateDecl> for ExternCrateId

fn from(ty: ExternCrateDecl) -> ExternCrateId

Converts to this type from the input type.

impl From<ExternCrateId> for ExternCrateDecl

fn from(id: ExternCrateId) -> ExternCrateDecl

Converts to this type from the input type.

impl HasAttrs for ExternCrateDecl

fn attrs(self, db: &dyn HirDatabase) -> AttrsWithOwner

impl HasContainer for ExternCrateDecl

fn container(&self, db: &dyn HirDatabase) -> ItemContainer

impl HasSource for ExternCrateDecl

type Ast = ExternCrate

fn source(self, db: &dyn HirDatabase) -> Option<InFile<Self::Ast>>

Fetches the definition’s source node. Using [crate::Semantics::source] is preferred when working with crate::Semantics, as that caches the parsed file in the semantics’ cache.

impl HasVisibility for ExternCrateDecl

fn visibility(&self, db: &dyn HirDatabase) -> Visibility

fn is_visible_from(&self, db: &dyn HirDatabase, module: Module) -> bool

impl Hash for ExternCrateDecl

fn hash<__H: Hasher>(&self, state: &mut __H)

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.

impl HirDisplay for ExternCrateDecl

fn hir_fmt(&self, f: &mut HirFormatter<'_>) -> Result<(), HirDisplayError>

fn into_displayable<'a>( &'a self, db: &'a dyn HirDatabase, max_size: Option<usize>, limited_size: Option<usize>, omit_verbose_types: bool, display_target: DisplayTarget, closure_style: ClosureStyle, show_container_bounds: bool, ) -> HirDisplayWrapper<'a, Self>

where Self: Sized,

Returns a Displayable type that is human-readable.

fn display<'a>( &'a self, db: &'a dyn HirDatabase, edition: Edition, ) -> HirDisplayWrapper<'a, Self>

where Self: Sized,

Returns a Displayable type that is human-readable. Use this for showing types to the user (e.g. diagnostics)

fn display_truncated<'a>( &'a self, db: &'a dyn HirDatabase, max_size: Option<usize>, edition: Edition, ) -> HirDisplayWrapper<'a, Self>

where Self: Sized,

Returns a Displayable type that is human-readable and tries to be succinct. Use this for showing types to the user where space is constrained (e.g. doc popups)

fn display_limited<'a>( &'a self, db: &'a dyn HirDatabase, limited_size: Option<usize>, edition: Edition, ) -> HirDisplayWrapper<'a, Self>

where Self: Sized,

Returns a Displayable type that is human-readable and tries to limit the number of items inside. Use this for showing definitions which may contain too many items, like trait, struct, enum

fn display_source_code<'a>( &'a self, db: &'a dyn HirDatabase, module_id: ModuleId, allow_opaque: bool, ) -> Result<String, DisplaySourceCodeError>

Returns a String representation of self that can be inserted into the given module. Use this when generating code (e.g. assists)

fn display_test<'a>( &'a self, db: &'a dyn HirDatabase, ) -> HirDisplayWrapper<'a, Self>

where Self: Sized,

Returns a String representation of self for test purposes

fn display_with_container_bounds<'a>( &'a self, db: &'a dyn HirDatabase, show_container_bounds: bool, edition: Edition, ) -> HirDisplayWrapper<'a, Self>

where Self: Sized,

Returns a String representation of self that shows the constraint from the container for functions

impl PartialEq for ExternCrateDecl

fn eq(&self, other: &ExternCrateDecl) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
