Function vmap::allocation_size

pub fn allocation_size() -> usize

Gets a cached version of the system allocation granularity size.

On Windows this value is typically 64k. Otherwise it is the same as the page size.

Examples

let alloc_size = vmap::allocation_size();
println!("the system allocation granularity is {} bytes", alloc_size);
if cfg!(windows) {
    assert!(alloc_size >= 65536);
} else {
    assert!(alloc_size >= 4096);
}
