Struct rkyv::with::AsVec

source · [−]

pub struct AsVec;

Expand description

A wrapper that serializes associative containers as a Vec of key-value pairs.

This provides faster serialization for containers like HashMap and BTreeMap by serializing the key-value pairs directly instead of building a data structure in the buffer.

Example

use std::collections::HashMap;
use rkyv::{Archive, with::AsVec};

#[derive(Archive)]
struct Example {
    #[with(AsVec)]
    values: HashMap<String, u32>,
}
