Struct WithSpan 

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

Struct used to wrap types with their associated “span” which is used when generating errors in the code generation.

Implementations

impl<T> WithSpan<T>

pub fn new(inner: T, span: impl Into<Span>) -> Self

pub const fn no_span(inner: T) -> Self

pub fn span(&self) -> Span

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

impl WithSpan<&str>

pub fn start(self) -> Self

Returns an empty Span that points to the start of the contained string.

pub fn end(self) -> Self

Returns an empty Span that points to the end of the contained string.

pub fn split_at(self, mid: usize) -> (Self, Self)

Splits self at mid into two spanned strings.
