Struct swc_common::errors::Handler [−][src]
pub struct Handler {
pub flags: HandlerFlags,
// some fields omitted
}
Expand description
A handler deals with errors; certain errors (fatal, bug, unimpl) may cause immediate exit, others log errors for later reporting.
Fields
flags: HandlerFlags
Implementations
Example implementation of Emitter is EmitterWriter
pub fn with_emitter_writer(
dst: Box<dyn Write + Send>,
cm: Option<Lrc<SourceMapperDyn>>
) -> Handler
pub fn with_emitter_writer(
dst: Box<dyn Write + Send>,
cm: Option<Lrc<SourceMapperDyn>>
) -> Handler
Calls Self::with_emitter with EmitterWriter.
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.

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
