Struct LintContext Copy item path

impl<'s> LintContext<'s>

pub fn new( sess: &'s Session, with_description: bool, config: InlineConfig, active_lints: Vec<&'static str>, ) -> Self

pub fn session(&self) -> &'s Session

pub fn is_lint_enabled(&self, id: &'static str) -> bool

pub fn emit<L: Lint>(&self, lint: &'static L, span: Span)

Helper method to emit diagnostics easily from passes

pub fn emit_with_fix<L: Lint>( &self, lint: &'static L, span: Span, snippet: Snippet, )

Emit a diagnostic with a code fix proposal.

For Diff snippets, if no span is provided, it will use the lint’s span. If unable to get code from the span, it will fall back to a Block snippet.

pub fn span_to_snippet(&self, span: Span) -> Option<String>

Gets the “raw” source code (snippet) of the given span.

pub fn get_span_indentation(&self, span: Span) -> usize

Gets the number of leading whitespaces (indentation) of the line where the span begins.
