pub trait SlabItem: Sized + Any {
const SLAB_SIZE: usize;
// Required methods
fn read_slab(index: usize, slab: &[u32]) -> Self;
fn write_slab(&self, index: usize, slab: &mut [u32]) -> usize;
}Expand description
Determines the “size” of a type when stored in a slab of &[u32],
and how to read/write it from/to the slab.
SlabItem can be automatically derived for struct and tuple types,
so long as those types’ fields implement SlabItem.
Required Associated Constants§
Required Methods§
Sourcefn write_slab(&self, index: usize, slab: &mut [u32]) -> usize
fn write_slab(&self, index: usize, slab: &mut [u32]) -> usize
Write the type into the slab at starting index and return
the new index.
If the type cannot be written, the returned index will be equal
to index.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
