Module panic_telemetry 

Structured panic telemetry for debugging Rust panics that become R errors.

Three separate panic→R-error paths exist in miniextendr (worker thread, ALTREP trampolines, and unwind_protect). This module provides a unified hook point that fires before each panic is converted to an R error.

Usage

use miniextendr_api::panic_telemetry::{set_panic_telemetry_hook, PanicReport, PanicSource};

set_panic_telemetry_hook(|report| {
    eprintln!("[{:?}] panic: {}", report.source, report.message);
});

Performance

fire() takes a read lock (uncontended in normal use). The hook only fires on panic paths, never on hot paths.

Structs

PanicReport

A structured panic report passed to the telemetry hook.

Enums

PanicSource

Describes where a panic originated before being converted to an R error.
