Error codes are integers, but `String` is used everywhere to represent
them. Gross!
This commit introduces `ErrCode`, an integral newtype for error codes,
replacing `String`. It also introduces a constant for every error code,
e.g. `E0123`, and removes the `error_code!` macro. The constants are
imported wherever used with `use rustc_errors::codes::*`.
With the old code, we have three different ways to specify an error code
at a use point:
```
error_code!(E0123) // macro call
struct_span_code_err!(dcx, span, E0123, "msg"); // bare ident arg to macro call
\#[diag(name, code = "E0123")] // string
struct Diag;
```
With the new code, they all use the `E0123` constant.
```
E0123 // constant
struct_span_code_err!(dcx, span, E0123, "msg"); // constant
\#[diag(name, code = E0123)] // constant
struct Diag;
```
The commit also changes the structure of the error code definitions:
- `rustc_error_codes` now just defines a higher-order macro listing the
used error codes and nothing else.
- Because that's now the only thing in the `rustc_error_codes` crate, I
moved it into the `lib.rs` file and removed the `error_codes.rs` file.
- `rustc_errors` uses that macro to define everything, e.g. the error
code constants and the `DIAGNOSTIC_TABLES`. This is in its new
`codes.rs` file.
Rename `EarlyErrorHandler` as `EarlyDiagCtxt`.2023-12-18T05:06:21+00:00Nicholas Nethercoten.nethercote@gmail.com2023-12-17T11:01:06+00:00urn:sha1:cce1701c4c3c37c96753ddb15fd822e71558d141rustc_log: provide a way to init logging based on the values, not names, of the env vars2023-11-11T14:24:33+00:00Ralf Jungpost@ralfj.de2023-11-11T12:34:20+00:00urn:sha1:581a317bbbbad807fd88eab490516787f1e9249eProvide more context for `rustc +nightly -Zunstable-options` on stable2023-06-27T15:23:33+00:00许杰友 Jieyou Xu (Joe)jieyouxu@outlook.com2023-06-22T21:56:09+00:00urn:sha1:cef812bd958d5037224aebe3721f3ffc9c80965erefactor: improve `error-index-generator` dependency2023-02-26T07:13:06+00:00Ezra Shawezrasure@outlook.com2023-02-25T09:59:20+00:00urn:sha1:53044158eff0d64673a6100f701c57b484232acarefactor: statically guarantee that current error codes are documented2023-02-26T07:12:36+00:00Ezra Shawezrasure@outlook.com2023-02-25T07:14:10+00:00urn:sha1:90677edcba063ee83316ef109e0fe54116015575fix: fix issue in macro2023-02-25T09:12:30+00:00Ezra Shawezrasure@outlook.com2023-02-25T09:12:30+00:00urn:sha1:3b51e9fde8e86e6a082922bc7db2f673ed981836error-index: Don't generate 404 instead of removing it.2023-01-05T19:07:35+00:00Eric Husseric@huss.org2023-01-05T14:44:11+00:00urn:sha1:72c3082aab3e2df801deeefcc65c7469d93274caFix error-index redirect to work with back button.2023-01-05T19:07:11+00:00Eric Husseric@huss.org2023-01-05T19:07:11+00:00urn:sha1:f2ad85a930539986517747729df6082553d195f8Fix tooltip display for error codes2022-09-17T22:32:28+00:00Guillaume Gomezguillaume.gomez@huawei.com2022-09-17T22:32:28+00:00urn:sha1:f45eacce76b76cd378948d9142d37c08ebdcf4d9
