Struct source_span::Loc

pub struct Loc<T: ?Sized> { /* fields omitted */ }

Located data.

This is a simple wrapper around data that can be located in a source file. It is useful to wrap abstract syntax tree nodes.

It derefs into the inner value.

Implementations

impl<T: ?Sized> Loc<T>

pub fn new(t: T, span: Span) -> Loc<T> where
    T: Sized, 

Associate a span location to some data by wrapping it under Loc.

pub fn span(&self) -> Span

Get the span location of the data.

pub fn inner_into<U>(self) -> Loc<U> where
    T: Into<U>, 

Convert the inner value.

pub fn inner_try_into<U>(self) -> Result<Loc<U>, <T as TryInto<U>>::Error> where
    T: TryInto<U>, 

Try to convert the inner value.

pub fn into_inner(self) -> T where
    T: Sized, 

Unwrap the data.

pub fn into_raw_parts(self) -> (T, Span) where
    T: Sized, 

Break the wrapper into the value and its location.
