Struct AttributeUsage 

pub struct AttributeUsage {
    pub name: String,
    pub typing: Option<String>,
    pub redefines: Option<String>,
    pub value: Option<Node<Expression>>,

}

Attribute usage: attribute name (:> | : type)? redefines? value? body.

Fields

name: String

typing: Option<String>

Type after : or :>, e.g. Some(“MassValue”).

redefines: Option<String>

Redefines target, e.g. Some(“Vehicle::mass”).

value: Option<Node<Expression>>

Value expression.

body: AttributeBody

name_span: Option<Span>

Span of the usage name (for semantic tokens).

typing_span: Option<Span>

Span of the type after : / :>, if present (for semantic tokens).

redefines_span: Option<Span>

Span of the redefines target after redefines, if present (for semantic tokens).

Trait Implementations

impl Clone for AttributeUsage

fn clone(&self) -> AttributeUsage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeUsage

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

Formats the value using the given formatter.

impl PartialEq for AttributeUsage

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