[−][src]Struct syntax::diagnostics::plugin::Handler
A handler deals with errors and other compiler output. Certain errors (fatal, bug, unimpl) may cause immediate exit, others log errors for later reporting.

[src]
pub fn reset_err_count(&self)
[src]
Resets the diagnostic error count as well as the cached emitted diagnostics.
NOTE: do not call this function from rustc. It is only meant to be called from external
tools that want to reuse a Parser
cleaning the previously emitted diagnostics as well as
the overall count of emitted error diagnostics.

pub fn must_teach(&self, code: &DiagnosticId) -> bool

true
if we haven't taught a diagnostic with this code already.
The caller must then teach the user about such a diagnostic.
Used to suppress emitting the same error multiple times with extended explanation when
calling -Zteach
