Struct Traceback 

pub struct Traceback { /* private fields */ }

A rendered error: the top-level message plus its Caused by: chain. Mirrors the role of rich.traceback.Traceback.

Implementations

impl Traceback

pub fn new(error: &dyn Error) -> Self

Build from an error, walking its Error::source chain.

pub fn from_message(message: impl Into<String>) -> Self

Build from a plain message (e.g. a captured panic string), with no chain.

Trait Implementations

impl Renderable for Traceback

fn rich_render( &self, console: &Console, options: &ConsoleOptions, ) -> Vec<Segment>

fn measure(&self, _console: &Console, options: &ConsoleOptions) -> Measurement

The (minimum, maximum) cell width this renderable wants. The default assumes the renderable fills the available width (e.g. Panel, Table); Text overrides it with its content width so the top-level print path can shrink to fit. Port of __rich_measure__ / Measurement.get.

fn fit_to_measurement(&self) -> bool

Whether a top-level Console::print shrinks this renderable to its measured width. The shrink stands in for upstream’s _collect_renderables, which joins printed str/Text values; other upstream renderables render at the full width, so one whose output pads to the width it is given (Syntax’s background) returns false.
