oxc-index-vec

Features

Usage

[dependencies]oxc_index ="3.1"# Enable optional features as needed:# oxc_index = { version = "3.1", features = ["serde", "nonmax"] }

Basic Index Type

use oxc_index::{IndexVec, define_index_type};define_index_type!{pubstructMyIdx =u32;}letmut vec:IndexVec<MyIdx,&str> =IndexVec::new();let idx = vec.push("hello");assert_eq!(vec[idx],"hello");

Memory-Efficient Index Type (requiresnonmax feature)

use oxc_index::{IndexVec, define_nonmax_u32_index_type};define_nonmax_u32_index_type!{pubstructCompactIdx;}// Option<CompactIdx> is the same size as CompactIdx (4 bytes)assert_eq!(    std::mem::size_of::<CompactIdx>(),    std::mem::size_of::<Option<CompactIdx>>());letmut vec:IndexVec<CompactIdx,String> =IndexVec::new();let idx = vec.push("world".to_string());

Serialization Support (requiresserde feature)

use oxc_index::{IndexVec, define_index_type};use serde::{Serialize,Deserialize};define_index_type!{pubstructMyIdx =u32;}#[derive(Serialize,Deserialize)]structMyData{items:IndexVec<MyIdx,String>,}
