Function lgalloc_stats

pub fn lgalloc_stats() -> LgAllocStats

Determine global statistics per size class.

This function is supposed to be relatively fast. It causes some syscalls, but they should be cheap (stat on a file descriptor).

Note that this function take a read lock on various structures. It calls fstat while holding a read lock on portions of the global state, which can block refills until the function returns.
