pub fn name(&self, db: &dyn HirDatabase) -> Name
pub fn index(&self) -> usize
sourcepub fn ty(&self, db: &dyn HirDatabase) -> Type
pub fn ty(&self, db: &dyn HirDatabase) -> Type
Returns the type as in the signature of the struct (i.e., with placeholder types for type parameters). Only use this in the context of the field definition.
pub fn layout(&self, db: &dyn HirDatabase) -> Result<Layout, LayoutError>
pub fn parent_def(&self, _db: &dyn HirDatabase) -> VariantDef

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.source§impl HasVisibility for Field

Use this for showing types to the user (e.g. diagnostics)source§fn display_truncated<'a>(

db: &'a (dyn HirDatabase + 'a),
max_size: Option<usize>
) -> HirDisplayWrapper<'a, Self>where
Self: Sized,
Returns a
Display
able 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)source§fn display_source_code<'a>(

) -> Result<String, DisplaySourceCodeError>
fn display_source_code<'a>(

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)source§fn display_test<'a>(
