Module options 

mimalloc’s mi_option_* settings: the runtime knobs behind every MIMALLOC_* environment variable.

Options are read once, lazily, the first time the allocator needs them, so setting one after the allocation it governs has already happened has no effect. In particular [Opt::SCAVENGER] and the profiler options must be set before the first allocation to matter; [Opt::PURGE_HOLES] and its companions are re-read per sweep and can be changed at any time.

use mimalloc_pprof::options::{self, Opt};
let previous = options::get(Opt::PURGE_HOLES_MIN_INTERVAL);
options::set(Opt::PURGE_HOLES_MIN_INTERVAL, 0); // sweep on every idle call
mimalloc_pprof::on_thread_idle();
options::set(Opt::PURGE_HOLES_MIN_INTERVAL, previous);
