Struct Backtrace 

pub struct Backtrace { /* private fields */ }

A captured OS thread stack backtrace.

Internally stores frames as a Box<[Frame]> (trimmed to actual length). Capture uses a stack-allocated scratch buffer so the FP walking loop itself is allocation-free; the single Box allocation happens only after the walk completes.

Implementations

impl Backtrace

pub fn capture() -> Self

Capture the current thread’s stack backtrace.

pub fn capture_trap(fp: usize, ip: usize, ra: usize) -> Self

Capture the stack backtrace from a trap.

• fp: frame pointer from the trap context
• ip: faulting instruction pointer (the PC from the trap frame)
• ra: return address (link register). On x86_64 this is always 0 since the return address is stored on the stack as part of the FP chain.

pub fn kind(self, kind: &'static str) -> Self

Sets the backtrace kind for machine-parseable raw output via [Display].

Trait Implementations

impl Clone for Backtrace

fn clone(&self) -> Backtrace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Backtrace

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

Formats the value using the given formatter.

impl Display for Backtrace

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

impl Eq for Backtrace

impl Ord for Backtrace

fn cmp(&self, other: &Backtrace) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Backtrace

fn eq(&self, other: &Backtrace) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Backtrace

fn partial_cmp(&self, other: &Backtrace) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
