pub struct Diagnostics { /* private fields */ }

Implementations

impl Diagnostics

pub fn new() -> Self

pub fn report( &mut self, kind: DiagnosticKind, range: TextRange, ) -> DiagnosticBuilder<'_>

Create a diagnostic with the given kind and span.

Uses the kind’s default message. Call .message() on the builder to override.

pub fn error( &mut self, msg: impl Into<String>, range: TextRange, ) -> DiagnosticBuilder<'_>

Create an error diagnostic (legacy API, prefer report()).

pub fn warning( &mut self, msg: impl Into<String>, range: TextRange, ) -> DiagnosticBuilder<'_>

Create a warning diagnostic (legacy API, prefer report()).

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn has_errors(&self) -> bool

pub fn has_warnings(&self) -> bool

pub fn error_count(&self) -> usize

pub fn warning_count(&self) -> usize

pub fn printer<'a>(&self, source: &'a str) -> DiagnosticsPrinter<'a>

pub fn filtered_printer<'a>(&self, source: &'a str) -> DiagnosticsPrinter<'a>

Printer that uses filtered diagnostics (cascading errors suppressed).

pub fn render(&self, source: &str) -> String

pub fn render_colored(&self, source: &str, colored: bool) -> String

pub fn render_filtered(&self, source: &str) -> String

pub fn render_filtered_colored(&self, source: &str, colored: bool) -> String

pub fn extend(&mut self, other: Diagnostics)
