Struct Spanning 

pub(crate) struct Spanning<T: ?Sized> {
    pub(crate) span: Span,
    pub(crate) item: T,
}

Wrapper for non-Spanned types to hold their Span.

Fields

span: Span

Span of the item.

item: T

Item the Span is held for.

Implementations

impl<T: ?Sized> Spanning<T>

pub(crate) const fn new(item: T, span: Span) -> Self

where T: Sized,

Creates a new Spanning item, attaching the provided Span to it.

pub fn into_inner(self) -> T

where T: Sized,

Destructures this Spanning wrapper returning the underlying item.

pub(crate) const fn span(&self) -> Span

Returns the Span contained in this Spanning wrapper.

pub(crate) const fn as_ref(&self) -> Spanning<&T>

Converts this &Spanning<T> into Spanning<&T> (moves the reference inside).

pub(crate) fn map<U>(self, f: impl FnOnce(T) -> U) -> Spanning<U>

where T: Sized,

Maps the wrapped item with the provided function, preserving the current Span.
