# Enum std::backtrace::BacktraceStatus

1.65.0 · source ·

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

Expand description

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

## Variants (Non-exhaustive)§

This enum is marked as 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.

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

#### 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.
