Struct Handle 

pub struct Handle { /* private fields */ }

Handle is a one-time token for inserting values into DeferredMap

Handle does not implement the Clone trait, ensuring it can only be used once through Rust’s move semantics.

Handle 是一次性令牌，用于向 DeferredMap 插入值

Handle 不实现 Clone trait，通过 Rust 的 move semantics 确保只能使用一次

Examples (示例)

use deferred_map::DeferredMap;
 
let mut map = DeferredMap::new();
let handle = map.allocate_handle();
let key = map.insert(handle, 42).unwrap();
assert_eq!(map.get(key), Some(&42));

Implementations

impl Handle

pub fn raw_value(&self) -> u64

Get the internal u64 value

获取内部的 u64 值

pub fn index(&self) -> u32

Extract index (lower 32 bits)

提取 index（低 32 位）

pub fn generation(&self) -> u32

Extract generation (upper 30 bits, excludes state bits)

提取 generation（高 30 位，不包含状态位）

Trait Implementations

impl Debug for Handle

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

Formats the value using the given formatter.

impl PartialEq for Handle

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