Trait Implementations

impl Clone for Variant

fn clone(&self) -> Variant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Variant

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

Formats the value using the given formatter.

impl From<&Variant> for SyntaxStablePtrId

fn from(node: &Variant) -> Self

Converts to this type from the input type.

impl Hash for Variant

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Variant

fn eq(&self, other: &Variant) -> 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 QueryAttrs for Variant

fn query_attr(&self, db: &dyn SyntaxGroup, attr: &str) -> Vec<Attribute>

Collect all attributes named exactly attr attached to this node.

fn find_attr(&self, db: &dyn SyntaxGroup, attr: &str) -> Option<Attribute>

Find first attribute named exactly attr attached do this node.

fn has_attr(&self, db: &dyn SyntaxGroup, attr: &str) -> bool

Check if this node has an attribute named exactly attr.

fn has_attr_with_arg( &self, db: &dyn SyntaxGroup, attr_name: &str, arg_name: &str, ) -> bool

Checks if the given object has an attribute with the given name and argument.

impl TypedSyntaxNode for Variant

const OPTIONAL_KIND: Option<SyntaxKind>

The relevant SyntaxKind. None for enums.

type StablePtr = VariantPtr

type Green = VariantGreen

fn missing(db: &dyn SyntaxGroup) -> Self::Green

fn from_syntax_node(db: &dyn SyntaxGroup, node: SyntaxNode) -> Self

fn cast(db: &dyn SyntaxGroup, node: SyntaxNode) -> Option<Self>
