Enum 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.
§1.65.0

Unsupported

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

§1.65.0

Disabled

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

§1.65.0

Captured

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