Function vmap::allocation_size [−][src]
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); }
