Struct Field 

pub struct Field { /* private fields */ }

Implementations

impl Field

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

pub fn index(&self) -> usize

pub fn ty<'db>(&self, db: &'db dyn HirDatabase) -> TypeNs<'db>

Returns the type as in the signature of the struct. Only use this in the context of the field definition.

pub fn ty_with_args<'db>( &self, db: &'db dyn HirDatabase, generics: impl Iterator<Item = Type<'db>>, ) -> Type<'db>

pub fn layout(&self, db: &dyn HirDatabase) -> Result<Layout, LayoutError>

pub fn parent_def(&self, _db: &dyn HirDatabase) -> VariantDef

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Field

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

Formats the value using the given formatter.

impl From<Field> for FieldId

fn from(def: Field) -> Self

Converts to this type from the input type.

impl From<FieldId> for Field

fn from(def: FieldId) -> Self

Converts to this type from the input type.

impl HasAttrs for Field

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

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

impl HasCrate for Field

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

impl HasSource for Field

type Ast = FieldSource

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

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.

impl HasVisibility for Field

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

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

impl Hash for Field

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 Field

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 Field

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

impl Copy for Field

impl Eq for Field

impl StructuralPartialEq for Field
