Trait Implementations

impl AsRef<str> for TyKind

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for TyKind

fn clone(&self) -> TyKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TyKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TyKind

fn deserialize<__D>( __deserializer: __D, ) -> Result<TyKind, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Literal> for TyKind

fn from(value: Literal) -> TyKind

Converts to this type from the input type.

impl From<PrimitiveSet> for TyKind

fn from(value: PrimitiveSet) -> TyKind

Converts to this type from the input type.

impl From<TyFunc> for TyKind

fn from(value: TyFunc) -> TyKind

impl PartialEq for TyKind

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

This method tests for self and other values to be equal, and is used by ==.

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
