Union coca::object::InlineStorage
source · [−]#[repr(C)]
pub union InlineStorage<A, const N: usize> {
/* private fields */
}This is supported on crate feature
unstable only.Expand description
An N-wide, partially initialized byte array with the alignment of A.
Examples
Note that its size in memory is always a multiple of its alignment, so it
is recommended to chose N accordingly:
use core::mem::{align_of, size_of};
use coca::object::{InlineStorage, Align16};
assert_eq!(align_of::<InlineStorage<Align16, 10>>(), 16);
assert_eq!(size_of::<InlineStorage<Align16, 10>>(), 16);
assert_eq!(size_of::<InlineStorage<Align16, 16>>(), 16);
assert_eq!(size_of::<InlineStorage<Align16, 20>>(), 32);Trait Implementations
