Struct VTable 

#[repr(C)]
pub struct VTable {
    pub size: usize,
    pub align: usize,
    pub drop_in_place: Option<unsafe extern "C" fn(*mut ())>,
    pub dealloc: Option<unsafe extern "C" fn(*mut ())>,
    pub _vfns: [unsafe extern "C" fn(*mut ()); 0],
}

A type which is layout compatible with a vtable from rfc 2955, but may not be relied upon to uphold the invariants of such a vtable

Fields

size: usize

The value of core::mem::size_of_val for the object

align: usize

The value of core::mem::align_of_val for the object

drop_in_place: Option<unsafe extern "C" fn(*mut ())>

If present, points to a function which performs the destructor operation for the type

dealloc: Option<unsafe extern "C" fn(*mut ())>

If present, points to a function which can deallocate pointers to this type

_vfns: [unsafe extern "C" fn(*mut ()); 0]

Each entry points to the implementation of each trait function which can be called on a trait object in the declaration order in the trait.
