Struct TypeDecl

pub struct TypeDecl {
    pub def_id: TypeDeclId,
    pub item_meta: ItemMeta,
    pub generics: GenericParams,
    pub kind: TypeDeclKind,
}

A type declaration.

Types can be opaque or transparent.

Transparent types are local types not marked as opaque. Opaque types are the others: local types marked as opaque, and non-local types (coming from external dependencies).

In case the type is transparent, the declaration also contains the type definition (see TypeDeclKind).

A type can only be an ADT (structure or enumeration), as type aliases are inlined in MIR.

Fields

def_id: TypeDeclId

item_meta: ItemMeta

Meta information associated with the item.

generics: GenericParams

kind: TypeDeclKind

The type kind: enum, struct, or opaque.

Trait Implementations

impl Clone for TypeDecl

fn clone(&self) -> TypeDecl

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TypeDecl

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TypeDecl

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Drive for TypeDecl

fn drive<V: Visitor>(&self, visitor: &mut V)

impl DriveMut for TypeDecl

fn drive_mut<V: VisitorMut>(&mut self, visitor: &mut V)

impl<C: AstFormatter> FmtWithCtx<C> for TypeDecl

fn fmt_with_ctx(&self, ctx: &C) -> String

fn fmt_with_ctx_and_indent(&self, _tab: &str, _ctx: &C) -> String

fn with_ctx<'a>(&'a self, ctx: &'a C) -> impl Display + 'a

Returns a struct that implements Display. This allows the following:

impl<'a> Formatter<&TypeDecl> for FmtCtx<'a>

fn format_object(&self, def: &TypeDecl) -> String

impl Serialize for TypeDecl

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
