Type Alias RuntimeStacktraceStringCallback 

pub type RuntimeStacktraceStringCallback = unsafe extern "C" fn(emit_stacktrace_string: unsafe extern "C" fn(*const c_char));

Function signature for runtime stacktrace string collection callbacks

This callback is invoked during crash handling in a signal context, so it must be signal-safe:

Parameters

• emit_stacktrace_string: Function to call for complete stacktrace string (takes C string)

Safety

The callback function is marked unsafe because:

• It receives function pointers that take raw pointers as parameters
• All C strings passed must be null-terminated and remain valid for the call duration
