Struct Spanned 

pub struct Spanned<T> { /* private fields */ }

A value paired with its source span.

The wrapper centralises span tracking so each AST kind enum can focus on its semantic variants without having to thread a span field through every variant manually.

Implementations

impl<T> Spanned<T>

pub fn new(value: T, span: Span) -> Self

Build a spanned value.

pub fn value(&self) -> &T

Borrow the inner value.

pub fn span(&self) -> Span

The span of this node.

pub fn into_parts(self) -> (T, Span)

Decompose into the inner value and its span.

pub fn map<U, F: FnOnce(T) -> U>(self, f: F) -> Spanned<U>

Map the inner value while preserving the span.
