Implementations§

source§

impl Diagnostic

source

pub fn new(level: Level, message: &str) -> Self

source

pub fn new_with_code( level: Level, code: Option<DiagnosticId>, message: &str, ) -> Self

source

pub fn is_error(&self) -> bool

source

pub fn cancel(&mut self)

Cancel the diagnostic (a structured diagnostic must either be emitted or canceled or it will panic when dropped).

source

pub fn cancelled(&self) -> bool

source

pub fn span_label<T: Into<String>>(&mut self, span: Span, label: T) -> &mut Self

Add a span/label to be included in the resulting snippet. This is pushed onto the MultiSpan that was created when the diagnostic was first built. If you don’t call this function at all, and you just supplied a Span to create the diagnostic, then the snippet will just include that Span, which is called the primary span.

pub fn span_suggestion_short( &mut self, sp: Span, msg: &str, suggestion: String, ) -> &mut Self

👎Deprecated: Use span_suggestion_short_with_applicability

Prints out a message with a suggested edit of the code. If the suggestion is presented inline it will only show the text message and not the text.

See CodeSuggestion for more information.

source

pub fn span_suggestion( &mut self, sp: Span, msg: &str, suggestion: String, ) -> &mut Self

👎Deprecated: Use span_suggestion_with_applicability

Prints out a message with a suggested edit of the code.

In case of short messages and a simple suggestion, rustc displays it as a label like

“try adding parentheses: (tup.0).1

The message

  • should not end in any punctuation (a : is added automatically)
  • should not be a question
  • should not contain any parts like “the following”, “as shown”
  • may look like “to do xyz, use” or “to do xyz, use abc”
  • may contain a name of a function, variable or type, but not whole expressions

See CodeSuggestion for more information.
