Struct TypeAlias

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

Fields

type_: Type

generics: Generics

inner_type: Option<TypeAliasInnerType>

Inner AdtDef type, ie type TyKind = IrTyKind<Adt, Ty>, to be shown directly on the typedef page.

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 guaranteed to come from metadata (and therefore hold the final type).

Trait Implementations

impl Clone for TypeAlias

fn clone(&self) -> TypeAlias

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TypeAlias

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

Formats the value using the given formatter.

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.
