Struct RichHandler 

pub struct RichHandler { /* private fields */ }

Renders log events like upstream’s RichHandler.

Implementations

impl RichHandler

pub fn new(console: Console) -> Self

A handler printing to console, with upstream’s defaults: time, level and path shown, repeated times omitted, ReprHighlighter, no markup, KEYWORDS highlighted and paths linked.

pub fn span_view(self, view: SpanView) -> Self

How an event’s spans are shown (default SpanView::Inline).

pub fn hyperlinker(self, hyperlinker: Hyperlinker) -> Self

Link the path column through hyperlinker instead of a bare file:// URL: its editor template, base directory for relative paths (as tracing reports them) and on/off switch apply.

pub fn live<W: Write + Send + 'static>( self, live: Arc<Mutex<LiveCoordinator<W>>>, ) -> Self

Print through live, above its regions, so log lines never tear a live display. Render with a console as wide as live’s target (see RenderTarget::console); longer lines fold. The coordinator refuses control codes, so any in a line (a message, field, span or path) are shown as symbols instead: every line prints.

pub fn show_time(self, show: bool) -> Self

Show the time column (upstream show_time).

pub fn show_level(self, show: bool) -> Self

Show the level column (upstream show_level).

pub fn show_path(self, show: bool) -> Self

Show the path column (upstream show_path).

pub fn omit_repeated_times(self, omit: bool) -> Self

Blank a time equal to the previous record’s (upstream omit_repeated_times).

pub fn level_width(self, width: Option<usize>) -> Self

The level column’s width, or None to fit (upstream log_time_format’s sibling level_width, fixed at 8 upstream).

pub fn markup(self, markup: bool) -> Self

Parse messages as console markup (upstream markup).

pub fn highlighter( self, highlighter: Option<Box<dyn Highlighter + Send + Sync>>, ) -> Self

The message highlighter, or None for none (upstream highlighter).

pub fn keywords<I, S>(self, keywords: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Words styled logging.keyword (upstream keywords).

pub fn enable_link_path(self, enable: bool) -> Self

Link the path column to the source file (upstream enable_link_path).

pub fn time_format( self, format: impl Fn() -> String + Send + Sync + 'static, ) -> Self

Format the current time for events without a timestamp (upstream log_time_format).

pub fn level_text(severity: Severity) -> Text

The level column. Port of RichHandler.get_level_text, with Python’s level names (WARNING, CRITICAL); TRACE uses logging.level.notset.

pub fn render_message(&self, event: &StructuredEvent) -> Text

The message column. Port of RichHandler.render_message; structured fields follow the message as key=value.

pub fn render(&self, event: &StructuredEvent) -> Table

Lay out one event. Port of RichHandler.render.

pub fn emit_event(&self, event: &StructuredEvent)

Print one event. Port of RichHandler.emit.
