Struct AttributeNode 

pub struct AttributeNode<'src> { /* private fields */ }

An attribute on an element.

Implementations

impl<'src> AttributeNode<'src>

pub fn new(source: &'src str, node: Node<'src>) -> Self

Create from source text and a matching tree-sitter node.

pub fn ts_node(&self) -> Node<'src>

The underlying tree-sitter node.

pub fn start(&self) -> usize

Byte offset of the start of this node.

pub fn end(&self) -> usize

Byte offset of the end of this node.

pub fn span(&self) -> Span

Span covering this node.

pub fn text(&self) -> &'src str

The raw source text of this node.

pub fn has_error(&self) -> bool

Whether this node has parse errors.

impl<'src> AttributeNode<'src>

pub fn name(&self) -> &'src str

The attribute name.

pub fn value_node(&self) -> Option<Node<'src>>

The attribute value node, if any.

pub fn is_shorthand(&self) -> bool

Whether this is a shorthand attribute ({identifier}).

pub fn is_spread(&self) -> bool

Whether this is a spread attribute ({...expr}).

pub fn is_directive(&self) -> bool

Whether this is a directive (e.g., bind:value, on:click).

pub fn directive_prefix(&self) -> Option<&'src str>

The directive prefix (e.g., “class” for class:active, “bind” for bind:value).

pub fn directive_name(&self) -> Option<&'src str>

For directives, the identifier after the colon (e.g., “active” in class:active).

pub fn is_class_directive(&self) -> bool

Whether this is a class:name directive.

pub fn is_bind_directive(&self) -> bool

Whether this is a bind:name directive.

pub fn is_style_directive(&self) -> bool

Whether this is a style:name directive.

pub fn has_shorthand_child(&self) -> bool

Whether this wraps a shorthand_attribute child node (both {name} and {...spread}).

pub fn static_value(&self) -> Option<&'src str>

The static text value of this attribute, if it’s a simple quoted or bare value.

pub fn value_expression<'c>( &self, cache: &'c ExpressionCache, ) -> Option<&'c Expression>

The value expression from the cache, if the value is an expression tag.

pub fn has_expression_value(&self) -> bool

Whether the value contains any expression (dynamic value).

pub fn has_mixed_value(&self) -> bool

Whether the value contains mixed text and expressions.

pub fn source_text(&self) -> &'src str

The source text that this attribute references.

pub fn value_parts(&self) -> Vec<AttributeValuePart<'src>>

Iterate over value parts as (is_expression: bool, text: &str, start_byte: usize). For quoted values like "foo {bar} baz", yields text and expression parts. For expression values like {expr}, yields one expression part. For boolean (no value), yields nothing.

Trait Implementations

impl<'src> Clone for AttributeNode<'src>

fn clone(&self) -> AttributeNode<'src>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeNode<'_>

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

Formats the value using the given formatter.
