Trait WrappingSpan 

pub trait WrappingSpan<T>: Span {
    type Spanned;

    // Required methods
    fn make_wrapped(self, inner: T) -> Self::Spanned;
    fn inner_of(spanned: &Self::Spanned) -> &T;
    fn span_of(spanned: &Self::Spanned) -> &Self;
}

A supertrait of Span that specifies how a value, usually an AST node, might have a span attached to it.

The type for which this trait is implemented is the span type, and the T is the value type.

Required Associated Types

type Spanned

The type of a node after being wrapped in a span.

Required Methods

fn make_wrapped(self, inner: T) -> Self::Spanned

Wrap a node in a span.

fn inner_of(spanned: &Self::Spanned) -> &T

Retrieve the inner value after it has been spanned.

fn span_of(spanned: &Self::Spanned) -> &Self

Retrieve the span of a spanned value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
