1//! This library is used to gather all error codes into one place, to make
2//! their maintenance easier.

8// This higher-order macro defines the error codes that are in use. It is used
9// in the `rustc_errors` crate. Removed error codes are listed in the comment
10// below.
11//
12// /!\ IMPORTANT /!\
13//
14// Error code explanation are defined in `error_codes/EXXXX.md` files. They must follow the RFC
15// 1567 available here:
16// https://rust-lang.github.io/rfcs/1567-long-error-codes-explanation-normalization.html
17//
18// Also, the contents of this macro is checked by tidy (in `check_error_codes_docs`). If you change
19// the macro syntax you will need to change tidy as well.
20//
21// Both columns are necessary because it's not possible in Rust to create a new identifier such as
22// `E0123` from an integer literal such as `0123`, unfortunately.
23//
24// Do *not* remove entries from this list. Instead, just add a note th the corresponding markdown
25// file saying that this error is not emitted by the compiler any more (see E0001.md for an
26// example), and remove all code examples that do not build any more.
