Utilities for interacting with the source text and manipulating spans. +//! +//! The main entry points for working with the source text are on the [`SpanExt`] trait. This trait +//! is implemented on a few types and exists as a bridge between a [`Span`] and the source text +//! backing it. The following are the main functions: +//! +//! * [`SpanExt::get_text`]: Gets a `SourceText` representing the text the span refers to. It works +//! very similarly to an `Arc`. +//! * [`SpanExt::check_text`]: A slightly simpler way to check a predicate on the text than using +//! `get_text`. +//! * [`SpanExt::map_range`]: The main way to adjust the range portion of a span or to split a span +//! into multiple ranges. See [`SpanEditCx`] for range adjustment utilities. +//! +//! When working with `Span`s it's important to make sure the they are from the correct +//! [`SyntaxContext`]. A `SyntaxContext` roughly corresponds to which desugaring or macro expansion +//! a `Span` is from. e.g. if `m!()` expands to `1 + 2` the binary operation and both literals will +//! have a `Span` with a `SyntaxContext` indicating that particular expansion of `m!`. To handle +//! moving up the chain of expansions use [`SpanExt::walk_to_ctxt`] or [`SpanExt::walk_to_root`]. +//! +//! # Warnings +//! +//! You _cannot_ assume anything about the `Span` or source text of any item. The parser will apply +//! token substitution in some cases (e.g. replacing `（`, with `(`), macros can rearrange tokens, +//! proc-macros in particular can freely set the `Span` of any token to a different one. These can +//! only be detected by checking the source text. With this the source text of all AST/HIR item can +//! be almost anything.
