Methods

impl<T> Spanned<T>

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

Wrap a given value together with the span it covers.

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

Trait Implementations

impl<T> HasSpan for Spanned<T>

fn span(&self) -> Span

Obtain the full span of the input file that this node covers.

fn human_span(&self) -> Span

Obtain a span which can be used to refer to this node in error messages presented to humans. This will generally be the name for things like entities, processes, and variables. Defaults to return whatever span() returns.

impl<T> HasDesc for Spanned<T> where     T: HasDesc,

fn desc(&self) -> &'static str

Obtain a human-readable descriptive name for this node.

fn desc_full(&self) -> String

Obtain a human-readable description for this node, possibly containing the node's name.
