Module proc_macro_error::multi

Facility to stack and emit multiple errors.

[abort!] macro stops a proc-macro right away, much like in a panic-like fashion. But sometimes you do not want to stop right there, for example you’re processing a list of attributes and want to emit a separate error for every mis-built attribute.

The [emit_error!] and [emit_call_site_error!] macros are just for it!

Functions

• abort_if_dirty
  Abort macro execution and display all the emitted errors, if any.
