Enum IdentKind 

pub enum IdentKind {
    Value,
    Type,
    Constant,
    Wildcard,
}

The shape bucket an identifier string belongs to.

Variants

Value

Binding name: let / fn / param / field / method / alias / module path segment / for-in var / pattern binding.

Type

Type name that isn’t pure-uppercase — Foo, Http, HttpClient, MyStruct, _Internal. Accepted at struct/enum/variant sites.

Constant

Pure-uppercase name — either a const declaration or a valid type name that happens to be all caps (FOO, X, HTTP, Dir::N). Accepted at struct/enum/variant sites and at const sites. Assigned-to in a source expression means “reassigning a constant” and is refused at parse time.

Wildcard

Pure-underscore identifier (_, __) — match wildcard and “explicitly discard” let (let _ = foo()).

Trait Implementations

impl Clone for IdentKind

fn clone(&self) -> IdentKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IdentKind

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

Formats the value using the given formatter.

impl PartialEq for IdentKind

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
