Enum std::backtrace::BacktraceStatus

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

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

回溯的当前状态，指示它是否已捕获或由于其他原因而为空。

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)

不支持捕获回溯，这可能是因为当前平台尚未实现。

Disabled

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

通过 RUST_LIB_BACKTRACE 或 RUST_BACKTRACE 环境变量已禁用捕获回溯。

Captured

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

回溯已被捕获，并且 Backtrace 在呈现时应打印合理的信息。
