Triggerable custom compiler error

Crates.io LICENSE

compiler_error is a rust compiler plugin that simply triggers a compilation error on demand and prints the token it receives, it is similar to the #error directive in the C preprocessor.

It is quite useful to provide helpful error message in macros with non-trival syntaxes.

Todo

  • support printing optionally multiple tokens
  • provide useful examples

No runtime deps
