Enum AnnotationTargetKind 

pub enum AnnotationTargetKind {
    Function,
    Type,
    Module,
    Expression,
    Block,
    AwaitExpr,
    Binding,
}

Describes what kind of syntax element an annotation is targeting. Used for compile-time validation of annotation applicability.

Variants

Trait Implementations

impl Clone for AnnotationTargetKind

fn clone(&self) -> AnnotationTargetKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnnotationTargetKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AnnotationTargetKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AnnotationTargetKind

fn eq(&self, other: &AnnotationTargetKind) -> 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.

impl Serialize for AnnotationTargetKind

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
