pub fn capture() -> Backtrace

Captures a stack backtrace of the current thread.

This function will capture a stack backtrace of the current OS thread of execution, returning a Backtrace type which can be later used to print the entire stack trace or render it to a string.

This function will be a noop if the RUST_BACKTRACE or RUST_LIB_BACKTRACE backtrace variables are both not set. If either environment variable is set and enabled then this function will actually capture a backtrace. Capturing a backtrace can be both memory intensive and slow, so these environment variables allow liberally using Backtrace::capture and only incurring a slowdown when the environment variables are set.

To forcibly capture a backtrace regardless of environment variables, use the Backtrace::force_capture function.

pub fn force_capture() -> Backtrace

Forcibly captures a full backtrace, regardless of environment variable configuration.

This function behaves the same as capture except that it ignores the values of the RUST_BACKTRACE and RUST_LIB_BACKTRACE environment variables, always capturing a backtrace.

Note that capturing a backtrace can be an expensive operation on some platforms, so this should be used with caution in performance-sensitive parts of code.

pub const fn disabled() -> Backtrace

Forcibly captures a disabled backtrace, regardless of environment variable configuration.

pub fn status(&self) -> BacktraceStatus

Returns the status of this backtrace, indicating whether this backtrace request was unsupported, disabled, or a stack trace was actually captured.

pub fn frames(&'a self) -> &'a [BacktraceFrame]

Returns an iterator over the backtrace frames.
