Struct rustdoc::clean::types::Typedef

pub(crate) struct Typedef {
    pub(crate) type_: Type,
    pub(crate) generics: Generics,
    pub(crate) item_type: Option<Type>,
}

Fields

type_: Type

generics: Generics

item_type: Option<Type>

type_ can come from either the HIR or from metadata. If it comes from HIR, it may be a type alias instead of the final type. This will always have the final type, regardless of whether type_ came from HIR or from metadata.

If item_type.is_none(), type_ is guarenteed to come from metadata (and therefore hold the final type).

Trait Implementations

impl Clone for Typedef

fn clone(&self) -> Typedef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Typedef

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

Formats the value using the given formatter.

impl FromWithTcx<Typedef> for Typedef

fn from_tcx(typedef: Typedef, tcx: TyCtxt<'_>) -> Self

impl GetDefId for Typedef

fn def_id(&self) -> Option<DefId>

Use this method to get the DefId of a clean AST node. This will return None when called on a primitive clean::Type. Use Self::def_id_full if you want to include primitives.

fn def_id_full(&self, cache: &Cache) -> Option<DefId>

Use this method to get the DefId of a clean AST node, including PrimitiveTypes.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
