# [−][src]Enum std::backtrace::BacktraceStatus

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

🔬 This is a nightly-only experimental API. (`backtrace` #53487)

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`
🔬 This is a nightly-only experimental API. (`backtrace` #53487)

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

`Disabled`
🔬 This is a nightly-only experimental API. (`backtrace` #53487)

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

`Captured`
🔬 This is a nightly-only experimental API. (`backtrace` #53487)

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