Struct rkyv::with::CopyOptimize

pub struct CopyOptimize;

A wrapper that provides specialized, performant implementations of serialization and deserialization.

This wrapper can be used with containers like Vec, but care must be taken to ensure that they contain copy-safe types. Copy-safe types must be trivially copyable (have the same archived and unarchived representations) and contain no padding bytes. In situations where copying uninitialized bytes the output is acceptable, this wrapper may be used with containers of types that contain padding bytes.

Safety

Using this wrapper with containers containing non-copy-safe types may result in undefined behavior.

Example

use rkyv::{Archive, with::CopyOptimize};

#[derive(Archive)]
struct Example {
    #[with(CopyOptimize)]
    bytes: Vec<u8>,
}
