Struct rkyv::with::RefAsBox

source ·
pub struct RefAsBox;
Expand description

A wrapper that serializes a reference as if it were boxed.

Unlike Inline, unsized references can be serialized with RefAsBox.

References serialized with RefAsBox cannot be deserialized because the struct cannot own the deserialized value.

§Example

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

#[derive(Archive)]
struct Example<'a> {
    #[with(RefAsBox)]
    a: &'a i32,
    #[with(RefAsBox)]
    b: &'a str,
}
