impl<'a, T> From<LocatedSpan<&'a str, T>> for MaybeSpanned<'a, T>

fn from(value: Spanned<'a, T>) -> Self

Converts to this type from the input type.

impl<T: Clone + 'static> StripCode for MaybeSpanned<'_, T>

type Stripped = LocatedSpan<CodeFragment<'static>, T>

Resulting type after code stripping.

fn strip_code(self) -> Self::Stripped
