Trait Implementations

impl Clone for EnumVariant

fn clone(&self) -> EnumVariant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EnumVariant

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

Formats the value using the given formatter.

impl From<&EnumVariant> for DefWithBodyId

fn from(v: &EnumVariant) -> Self

Converts to this type from the input type.

impl From<EnumVariant> for DefWithBody

fn from(it: EnumVariant) -> DefWithBody

Converts to this type from the input type.

impl From<EnumVariant> for EnumVariantId

fn from(def: EnumVariant) -> Self

Converts to this type from the input type.

impl From<EnumVariant> for ModuleDef

fn from(it: EnumVariant) -> ModuleDef

Converts to this type from the input type.

impl From<EnumVariant> for Variant

fn from(it: EnumVariant) -> Variant

Converts to this type from the input type.

impl From<EnumVariantId> for EnumVariant

fn from(id: EnumVariantId) -> Self

Converts to this type from the input type.

impl HasAttrs for EnumVariant

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

fn hir_docs(self, db: &dyn HirDatabase) -> Option<&Docs>

impl HasCrate for EnumVariant

fn krate(&self, db: &dyn HirDatabase) -> Crate

impl HasName for EnumVariant

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

impl HasSource for EnumVariant

type Ast = Variant

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

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

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

Fetches the source node, along with its full range.

impl HasVisibility for EnumVariant

Variants inherit visibility from the parent enum.

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

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

impl Hash for EnumVariant

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<'db> HirDisplay<'db> for EnumVariant

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

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

where Self: Sized,

Returns a Displayable type that is human-readable.

fn display<'a>( &'a self, db: &'db (dyn HirDatabase + 'static), display_target: DisplayTarget, ) -> HirDisplayWrapper<'a, 'db, 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: &'db (dyn HirDatabase + 'static), max_size: Option<usize>, display_target: DisplayTarget, ) -> HirDisplayWrapper<'a, 'db, 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: &'db (dyn HirDatabase + 'static), limited_size: Option<usize>, display_target: DisplayTarget, ) -> HirDisplayWrapper<'a, 'db, 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: &'db (dyn HirDatabase + 'static), module_id: ModuleIdLt<'static>, 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: &'db (dyn HirDatabase + 'static), display_target: DisplayTarget, ) -> HirDisplayWrapper<'a, 'db, Self>

where Self: Sized,

Returns a String representation of self for test purposes

fn display_with_container_bounds<'a>( &'a self, db: &'db (dyn HirDatabase + 'static), show_container_bounds: bool, display_target: DisplayTarget, ) -> HirDisplayWrapper<'a, 'db, Self>

where Self: Sized,

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

impl PartialEq for EnumVariant

fn eq(&self, other: &EnumVariant) -> 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.
