Enum tracing_core::stdlib::backtrace::BacktraceStatus

#[non_exhaustive]
pub enum BacktraceStatus {
    Unsupported,
    Disabled,
    Captured,
}

The current status of a backtrace, indicating whether it was captured or whether it is empty for some other reason.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unsupported

Capturing a backtrace is not supported, likely because it’s not implemented for the current platform.

Disabled

Capturing a backtrace has been disabled through either the RUST_LIB_BACKTRACE or RUST_BACKTRACE environment variables.

Captured

A backtrace has been captured and the Backtrace should print reasonable information when rendered.

Trait Implementations

impl Debug for BacktraceStatus

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

Formats the value using the given formatter.

impl PartialEq for BacktraceStatus

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
