Struct swh_graph::utils::mmap::NumberMmap

pub struct NumberMmap<E: ByteOrder, N: AsBytes, B> { /* private fields */ }

Newtype for [Mmap] used to store arrays of any integers

instead of slices of u8

Implementations

Trait Implementations

impl<E: ByteOrder> GetIndex for &NumberMmap<E, i16, Mmap>

fn get(&self, index: usize) -> Option<i16>

Returns an item
