Required Methods

fn level(&self) -> DiagnosticLevel

The level of the diagnostic.

fn code(&self) -> Cow<'_, str>

The diagnostic code, like no-explicit-any or ban-untagged-ignore.

fn message(&self) -> Cow<'_, str>

The human-readable diagnostic message.

fn location(&self) -> DiagnosticLocation<'_>

The location this diagnostic is associated with.

fn snippet(&self) -> Option<DiagnosticSnippet<'_>>

A snippet showing the source code associated with the diagnostic.

fn hint(&self) -> Option<Cow<'_, str>>

A hint for fixing the diagnostic.

fn snippet_fixed(&self) -> Option<DiagnosticSnippet<'_>>

A snippet showing how the diagnostic can be fixed.

fn info(&self) -> Cow<'_, [Cow<'_, str>]>

fn docs_url(&self) -> Option<Cow<'_, str>>

An optional URL to the documentation for the diagnostic.

Provided Methods

fn display(&self) -> DiagnosticDisplay<'_, Self>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
