Struct ra_ap_hir::Field

pub struct Field { /* fields omitted */ }

Implementations

impl Field

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

pub fn signature_ty(&self, db: &dyn HirDatabase) -> Type

Returns the type as in the signature of the struct (i.e., with placeholder types for type parameters). This is good for showing signature help, but not so good to actually get the type of the field when you actually have a variable of the struct.

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

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Field

impl Debug for Field

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

Formats the value using the given formatter.

impl Eq for Field

impl From<FieldId> for Field

fn from(def: FieldId) -> Self

Performs the conversion.

impl HasAttrs for Field

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

fn docs(self, db: &dyn HirDatabase) -> Option<Documentation>

fn resolve_doc_path(
    self,
    db: &dyn HirDatabase,
    link: &str,
    ns: Option<Namespace>
) -> Option<ModuleDef>

impl HasSource for Field

type Ast = FieldSource

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

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.

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

Feeds a slice of this type into the given Hasher.

impl HirDisplay for Field

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

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

Returns a Displayable type that is human-readable.

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

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

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

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)

pub fn display_source_code(
    &'a self,
    db: &'a (dyn HirDatabase + 'a),
    module_id: ModuleId
) -> 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)

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

Returns a String representation of self for test purposes

impl PartialEq<Field> for Field

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
