Type Alias Generation 

pub type Generation = Opaque<u64>;

Opaque is a replacement for integral T in cases where only comparisons must be supported, and it’s desirable to prevent accidental dependency on exact values.

Aliased Type

#[repr(C)]
pub struct Generation {
    pub _phantom_0: PhantomData<UnsafeCell<u64>>,
    pub mValue: u64,
}

Fields

_phantom_0: PhantomData<UnsafeCell<u64>>

mValue: u64

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
