Struct rustc_ap_rustc_errors::Handler [−][src]
pub struct Handler { /* fields omitted */ }
Expand description
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 with_emitter(

treat_err_as_bug: Option<NonZeroUsize>,
emitter: Box<dyn Emitter + Send>
) -> 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.
Stash a given diagnostic with the given Span
and StashKey
as the key for later stealing.
Steal a previously stashed diagnostic with the given Span
and StashKey
as the key.
Emit all stashed diagnostics.
Construct a dummy builder with Level::Cancelled
.
Using this will neither report anything to the user (e.g. a warning), nor will compilation cancel as a result.

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
