Implementations

impl DefaultKey

pub fn new(index: u32, generation: Generation, map_id: u64) -> Self

Create a new Key from index and generation

从 index 和 generation 创建新的 Key

pub fn decode(&self) -> (u32, Generation)

Decode Key into index and generation

将 Key 解码为 index 和 generation

Trait Implementations

impl Clone for DefaultKey

fn clone(&self) -> DefaultKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DefaultKey

impl Debug for DefaultKey

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

Formats the value using the given formatter.

impl Eq for DefaultKey

impl Hash for DefaultKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Key for DefaultKey

type Raw = u64

unsafe fn from_raw(raw: Self::Raw, map_id: u64) -> Self

fn from_parts(index: u32, generation: Generation, map_id: u64) -> Self

fn index(&self) -> u32

fn generation(&self) -> Generation

fn raw(&self) -> Self::Raw

fn map_id(&self) -> u64

impl PartialEq for DefaultKey

fn eq(&self, other: &DefaultKey) -> 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.
