Enum Hash 

#[repr(i32)]
pub enum Hash {
    InternalHash = 1,
    Phash2 = 2,
}

The hash algorithm selector for hash.

Chooses between a fast non-portable internal hash and the portable phash2 that matches erlang:phash2/1.

Variants

InternalHash = 1

Non-portable internal hash; fast, but may change between ERTS versions.

ERL_NIF_INTERNAL_HASH — NIF 2.12 — OTP 20

Phash2 = 2

Portable phash2 hash, matching erlang:phash2/1.

ERL_NIF_PHASH2 — NIF 2.12 — OTP 20

Trait Implementations

impl Clone for Hash

fn clone(&self) -> Hash

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Hash

impl Debug for Hash

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Hash

impl PartialEq for Hash

fn eq(&self, other: &Hash) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
