[−][src]Struct rustc_ap_rustc_errors::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.

pub fn set_continue_after_error(&self, continue_after_error: bool)
[src]
pub fn can_emit_warnings(&self) -> bool
[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 stash_diagnostic(&self, span: Span, key: StashKey, diag: Diagnostic)
[src]
Stash a given diagnostic with the given Span
and StashKey
as the key for later stealing.
If the diagnostic with this (span, key)
already exists, this will result in an ICE.
pub fn steal_diagnostic(
&self,
span: Span,
key: StashKey
) -> Option<DiagnosticBuilder>
[src]
&self,
span: Span,
key: StashKey
) -> Option<DiagnosticBuilder>
Steal a previously stashed diagnostic with the given Span
and StashKey
as the key.
pub fn emit_stashed_diagnostics(&self)
[src]
Emit all stashed diagnostics.
pub fn struct_dummy(&self) -> DiagnosticBuilder
[src]
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.
pub fn struct_span_warn(
&self,
span: impl Into<MultiSpan>,
msg: &str
) -> DiagnosticBuilder
[src]
&self,
span: impl Into<MultiSpan>,
msg: &str
) -> DiagnosticBuilder
Construct a builder at the Warning
level at the given span
and with the msg
.
pub fn struct_span_warn_with_code(
&self,
span: impl Into<MultiSpan>,
msg: &str,
code: DiagnosticId
) -> DiagnosticBuilder
[src]
&self,
span: impl Into<MultiSpan>,
msg: &str,
code: DiagnosticId
) -> DiagnosticBuilder
Construct a builder at the Warning
level at the given span
and with the msg
.
Also include a code.
pub fn struct_warn(&self, msg: &str) -> DiagnosticBuilder
[src]
Construct a builder at the Warning
level with the msg
.
pub fn struct_span_err(
&self,
span: impl Into<MultiSpan>,
msg: &str
) -> DiagnosticBuilder
[src]
&self,
span: impl Into<MultiSpan>,
msg: &str
) -> DiagnosticBuilder
Construct a builder at the Error
level at the given span
and with the msg
.

&self,
span: impl Into<MultiSpan>,
msg: &str,
code: DiagnosticId
) -> DiagnosticBuilder
[src]
&self,
span: impl Into<MultiSpan>,
msg: &str,
code: DiagnosticId
) -> DiagnosticBuilder
Construct a builder at the Error
level at the given span
, with the msg
, and code
.
pub fn struct_err(&self, msg: &str) -> DiagnosticBuilder
[src]
Construct a builder at the Error
level with the msg
.

) -> DiagnosticBuilder
[src]
&self,
msg: &str,

Construct a builder at the Error
level with the msg
and the code
.

&self,
span: impl Into<MultiSpan>,
msg: &str
) -> DiagnosticBuilder
[src]
&self,
span: impl Into<MultiSpan>,
msg: &str
) -> DiagnosticBuilder
Construct a builder at the Fatal
level at the given span
and with the msg
.

&self,
span: impl Into<MultiSpan>,
msg: &str,
code: DiagnosticId
) -> DiagnosticBuilder
[src]
&self,

calling -Zteach
