-//! A trait that can provide the `Span` of the complete contents of a syntax
-//! tree node.
-//!
-//! <br>
-//!
-//! # Example
-//!
-//! Suppose in a procedural macro we have a [`Type`] that we want to assert
-//! implements the [`Sync`] trait. Maybe this is the type of one of the fields
-//! of a struct for which we are deriving a trait implementation, and we need to
-//! be able to pass a reference to one of those fields across threads.
-//!
-//! [`Type`]: crate::Type
-//! [`Sync`]: std::marker::Sync
-//!
-//! If the field type does *not* implement `Sync` as required, we want the
-//! compiler to report an error pointing out exactly which type it was.
-//!
-//! The following macro code takes a variable `ty` of type `Type` and produces a
-//! static assertion that `Sync` is implemented for that type.
-//!
-//! ```
-//! # extern crate proc_macro;
-//! #
-//! use proc_macro::TokenStream;
-//! use proc_macro2::Span;
-//! use quote::quote_spanned;
-//! use syn::Type;
-//! use syn::spanned::Spanned;
-//!
-//! # const IGNORE_TOKENS: &str = stringify! {
-//! #[proc_macro_derive(MyMacro)]
-//! # };
-//! pub fn my_macro(input: TokenStream) -> TokenStream {
-//!     # let ty = get_a_type();
-//!     /* ... */
-//!
-//!     let assert_sync = quote_spanned! {ty.span()=>
-//!         struct _AssertSync where #ty: Sync;
-//!     };
-//!
-//!     /* ... */
-//!     # input
-//! }
-//! #
-//! # fn get_a_type() -> Type {
-//! #     unimplemented!()
-//! # }
-//! ```
-//!
-//! By inserting this `assert_sync` fragment into the output code generated by
-//! our macro, the user's code will fail to compile if `ty` does not implement
-//! `Sync`. The errors they would see look like the following.
-//!
-//! ```text
-//! error[E0277]: the trait bound `*const i32: std::marker::Sync` is not satisfied
-//!   --> src/main.rs:10:21
-//!    |
-//! 10 |     bad_field: *const i32,
-//!    |                ^^^^^^^^^^ `*const i32` cannot be shared between threads safely
-//! ```
-//!
-//! In this technique, using the `Type`'s span for the error message makes the
-//! error appear in the correct place underlining the right type.
-//!
-//! <br>
-//!
-//! # Limitations
-//!
-//! The underlying [`proc_macro::Span::join`] method is nightly-only. When
-//! called from within a procedural macro in a nightly compiler, `Spanned` will
-//! use `join` to produce the intended span. When not using a nightly compiler,
-//! only the span of the *first token* of the syntax tree node is returned.
-//!
-//! In the common case of wanting to use the joined span as the span of a
-//! `syn::Error`, consider instead using [`syn::Error::new_spanned`] which is
-//! able to span the error correctly under the complete syntax tree node without
-//! needing the unstable `join`.
-//!
-//! [`syn::Error::new_spanned`]: crate::Error::new_spanned
