Struct MemStats 

pub struct MemStats {
    pub live_bytes: u64,
    pub peak_bytes: u64,
    pub alloc_count: u64,
    pub free_count: u64,
}

A snapshot of the tracked heap. Counters are relaxed, so the fields are individually accurate but need not agree with each other to the byte under concurrent allocation.

Fields

live_bytes: u64

Bytes currently allocated and not yet freed.

peak_bytes: u64

High-water mark of live_bytes, sampled as the shards are re-summed.

alloc_count: u64

Allocations made since process start. With free_count, this is the churn rate; a reallocation resizes an existing block and counts as neither.

free_count: u64

Frees made since process start.
