Struct Stack 

pub struct Stack {
    pub exc_type: String,
    pub exc_value: String,
    pub syntax_error: Option<SyntaxErrorInfo>,
    pub is_cause: bool,
    pub frames: Vec<Frame>,
}

A single exception stack (one exception in a chain).

Contains the exception type, value, optional syntax error info, and the list of frames leading to the exception.

Fields

exc_type: String

The exception type name (e.g., “ValueError”, “RuntimeError”).

exc_value: String

The exception message/value.

syntax_error: Option<SyntaxErrorInfo>

Syntax error information (for SyntaxError exceptions).

is_cause: bool

Whether this exception was caused by another (chained exception).

frames: Vec<Frame>

The stack frames for this exception.

Implementations

impl Stack

pub fn new(exc_type: impl Into<String>, exc_value: impl Into<String>) -> Self

Create a new stack with the exception type and value.

Arguments

• exc_type - The exception type name.
• exc_value - The exception message.

Example

use rich_rs::traceback::Stack;

let stack = Stack::new("ValueError", "invalid input");

pub fn with_syntax_error(self, error: SyntaxErrorInfo) -> Self

Set the syntax error info.

pub fn with_is_cause(self, is_cause: bool) -> Self

Mark this as a caused exception (from exception chaining).

pub fn with_frames(self, frames: Vec<Frame>) -> Self

Set the frames for this stack.

pub fn with_frame(self, frame: Frame) -> Self

Add a single frame to the stack.

pub fn add_frame(&mut self, frame: Frame)

Add a frame to the stack (mutable version).

pub fn is_syntax_error(&self) -> bool

Check if this is a syntax error.

pub fn frame_count(&self) -> usize

Get the number of frames.

Trait Implementations

impl Clone for Stack

fn clone(&self) -> Stack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stack

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

Formats the value using the given formatter.
