Trait SyntaxNode 

pub trait SyntaxNode {
    // Provided methods
    fn span(&self) -> Option<Span> { ... }
    fn ident(&self) -> Option<Ident> { ... }
    fn attributes(&self) -> &[AttributeNode]  { ... }
    fn attributes_mut(&mut self) -> &mut [AttributeNode]  { ... }
    fn contains_attribute(&self, attribute: &Attribute) -> bool { ... }
    fn retain_attributes_mut<F>(&mut self, _predicate: F)
       where F: FnMut(&mut Attribute) -> bool { ... }
}

Trait implemented for all syntax node types.

This trait is useful for generic implementations over different syntax node types. Node types that do not have a span, an ident, or attributes return None.

Provided Methods

fn span(&self) -> Option<Span>

Span of a syntax node.

fn ident(&self) -> Option<Ident>

Identifier, if the syntax node is a declaration.

fn attributes(&self) -> &[AttributeNode]

List all attributes of a syntax node.

fn attributes_mut(&mut self) -> &mut [AttributeNode]

List all attributes of a syntax node.

fn contains_attribute(&self, attribute: &Attribute) -> bool

Whether the node contains an attribute.

fn retain_attributes_mut<F>(&mut self, _predicate: F)

where F: FnMut(&mut Attribute) -> bool,

Remove attributes with predicate.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
