Module panic_hook 

Process-wide reporting of panics.

Tokio catches a panic at the task boundary and hands it to whoever joins the task, so a panicking task neither stops the runtime nor, on its own, produces anything a monitoring system can act on: the default hook writes to standard error and nothing else. The hook installed here reports the panic through tracing and the metrics registry first, so that panics are visible wherever the process’s other logs and metrics are collected.

Functions

init

Installs a panic hook that reports panics through tracing and the metrics registry before delegating to the hook that was previously installed.
