Struct Spanned 

pub(crate) struct Spanned<T> {
    pub(crate) t: T,
    pub(crate) span: Span,
}

A value with an associated span.

Fields

t: T

span: Span

Implementations

impl<T> Spanned<T>

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

pub(super) fn from<U>(s: Spanned<U>) -> Spanned<T>

where T: From<U>,

pub(super) fn try_from<E, U>( u: Spanned<U>, ) -> Result<Spanned<T>, FromRawReprError<Spanned<E>>>

where T: TryFrom<U, Error = FromRawReprError<E>>,

Delegates to T: TryFrom, preserving span information in both the success and error cases.
