#[derive(Pod)]Expand description
Deriving Pod trait for a struct or union.
When deriving the Pod trait,
this macro performs a safety check because the Pod trait is marked as unsafe.
For structs and unions,
the macro checks that the struct has a valid repr attribute (e.g., repr(C), repr(u8)),
and each field is of Pod type.
Enums cannot implement the Pod trait.
If you want to implement Pod
for a struct or union with fields that are not of Pod type,
you can implement it unsafely and perform the necessary checks manually.
