codespan_reporting::diagnostic::Diagnostic now implements Debug.Single-line labels are now rendered together, under the same source line.
For example:
┌── one_line.rs:3:5 ─── │ 3 │ v.push(v.pop().unwrap()); │ - first borrow later used by call · 3 │ v.push(v.pop().unwrap()); │ ---- first mutable borrow occurs here · 3 │ v.push(v.pop().unwrap()); │ ^ second mutable borrow occurs here │

codespan_reporting::files module was added as a way to decouple codespan_reporting from codespan.codespan_reporting::files::Files allows users to implement custom file databases that work with codespan_reporting. This should make it easier to integrate with libraries like Salsa, and also makes it less invasive to use codespan_reporting on existing projects.codespan_reporting::files::SimpleFile is a simple implementation of codespan_reporting::files::Files where only a single file is needed.codespan_reporting::files::SimpleFiles is a simple implementation of codespan_reporting::files::Files where multiple files are needed.codespan_reporting::diagnostic module has been greatly revamped, making the builder API format more nicely with rustfmt, and allowing for multiple primary labels.codespan_reporting::term::emit was improved, with the following changes:codespan_reporting::term::emit now takes writers as a trait object (rather than using static dispatch) in order to reduce coda bloat and improve compile times.codespan_reporting::term::Chars were tweaked for consistency.codespan_reporting no longer depends on codespan. Note that codespan can still be used with codespan_reporting, as codespan::Files now implements codespan_reporting::files::Files.
