Examples
use core::mem::MaybeUninit; use rkyv::out_field; struct Example { a: i32, b: bool, } let mut result = MaybeUninit::<Example>::zeroed(); let out = result.as_mut_ptr(); let (a_off, a) = out_field!(out.a); unsafe { a.write(42); } let (b_off, b) = out_field!(out.b); unsafe { b.write(true); } let result = unsafe { result.assume_init() }; assert_eq!(result.a, 42); assert_eq!(result.b, true);
