std-ext

English | 简体中文

std-ext extends the Rust standard library with additional traits and utilities for common patterns, making standard types more convenient to use.

Features

• ArcExt trait — wrap any value in Arc via .arc()
• AtomicExt trait — convert primitives to atomic types
• CacheMapExt — TTL-based cache for HashMap, BTreeMap, DequeBTreeMap, DequeHashMap
• EntryExt — extended Entry API with TTL support
• TimedValue — value wrapper with expiration
• OrdExt / HashExt / OrdHashExt — ordering and hashing wrappers
• Tuple helper macros: tuple_deref!, tuple_deref_mut!, tuple_take!

Basic Usage

use std_ext::{ArcExt, AtomicExt};
use std::sync::atomic::Ordering;

// Wrap in Arc
let v = 42.arc();
assert_eq!(*v, 42);

// Convert to atomic
let a = 0usize.atomic();
a.store(10, Ordering::SeqCst);
assert_eq!(a.load(Ordering::SeqCst), 10);

Tests
