Function libmimalloc_sys::mi_collect

pub unsafe extern "C" fn mi_collect(force: bool)

Eagerly free memory.

If force is true, aggressively return memory to the OS (can be expensive!)

Regular code should not have to call this function. It can be beneficial in very narrow circumstances; in particular, when a long running thread allocates a lot of blocks that are freed by other threads it may improve resource usage by calling this every once in a while.
