Local-affinity first NUMA-aware allocator with optional fallback.

This crate supplies NUMA-aware local policy enabled allocation.

When using autoselect

Fallback system is triggered with autoselect. If system is not supporting NUMA-aware allocation it falls back to Jemalloc.

When using NUMA-aware

If autoselect is not used, memmap fallback will be triggered with default system page size and it will be used as allocator.

// Allocator generator macro
use numanji::*;

// Do autoselect for allocator
autoselect!();

fn main() {
    // Allocated by Numanji based on your Numa availability on your system.
    let _vec = Vec::<usize>::with_capacity(1234);
}
