Struct Traceback 

pub struct Traceback { /* private fields */ }

Renders a traceback with Rich formatting.

Mimics Python Rich’s rich.traceback.Traceback renderable.

Implementations

impl Traceback

pub fn new(trace: Trace) -> Self

Create a new Traceback from Trace data.

pub fn from_exception( exc_type: impl Into<String>, exc_value: impl Into<String>, frames: Vec<Frame>, ) -> Self

Convenience constructor: build a Traceback from an exception type, value, and list of frames.

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

Builder: set the total output width in characters.

pub fn code_width(self, width: usize) -> Self

Builder: set the width reserved for source code (excluding line numbers).

pub fn extra_lines(self, n: usize) -> Self

Builder: set the number of extra source lines shown before and after the error line.

pub fn theme(self, theme: impl Into<String>) -> Self

Builder: set the theme name (e.g. "monokai", "base16-ocean.dark").

pub fn word_wrap(self, wrap: bool) -> Self

Builder: enable or disable word wrapping of long lines.

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

Builder: show local variables at each frame when set to true.

pub fn indent_guides(self, guides: bool) -> Self

Builder: enable indentation guides in source context.

pub fn locals_max_length(self, n: usize) -> Self

Builder: set the maximum number of local variables to display per frame.

pub fn locals_max_string(self, n: usize) -> Self

Builder: set the maximum length for local variable string values.

pub fn locals_max_depth(self, n: usize) -> Self

Builder: set the maximum depth for nested local variable display.

pub fn locals_hide_dunder(self, hide: bool) -> Self

Builder: hide locals with dunder names (e.g. __name__) when true.

pub fn locals_hide_sunder(self, hide: bool) -> Self

Builder: hide locals with underscore-prefixed names (e.g. _secret) when true.

pub fn suppress(self, suppress: Vec<String>) -> Self

Builder: suppress frames whose filename matches any of the given patterns.

pub fn max_frames(self, n: usize) -> Self

Builder: limit the number of frames shown (remaining are collapsed into a single message).

Trait Implementations

impl Clone for Traceback

fn clone(&self) -> Traceback

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Traceback

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Renderable for Traceback

fn render(&self, options: &ConsoleOptions) -> RenderResult

Render this object into a RenderResult using the provided options.

fn measure(&self, _options: &ConsoleOptions) -> Option<Measurement>

Optional width-measurement hook (equivalent to __rich_measure__). Override to provide min/max width constraints for layout.
