Function fault_injection::set_trigger_function

pub fn set_trigger_function(
    f: fn(crate_name: &'static str, file_name: &'static str, line_number: u32)
)

This function will be called any time the FAULT_INJECT_COUNTER reaches 0 and an error is injected. You can use this to re-set the counter for deep fault tree enumeration, test auditing, etc…

The function accepts the crate name, file name, and line number as arguments.
