Struct tract_nnef::internal::tract_downcast_rs::__std::backtrace::Backtrace[][src]

pub struct Backtrace { /* fields omitted */ }
🔬 This is a nightly-only experimental API. (backtrace)

A captured OS thread stack backtrace.

This type represents a stack backtrace for an OS thread captured at a previous point in time. In some instances the Backtrace type may internally be empty due to configuration. For more information see Backtrace::capture.

Implementations

impl Backtrace[src]

pub fn capture() -> Backtrace[src]

🔬 This is a nightly-only experimental API. (backtrace)

Capture 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[src]

🔬 This is a nightly-only experimental API. (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[src]

🔬 This is a nightly-only experimental API. (backtrace)

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

pub fn status(&self) -> BacktraceStatus[src]

🔬 This is a nightly-only experimental API. (backtrace)

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