Struct libreda_db::index::Index

pub struct Index<T, Int = u32> {
    index: Int,
    phantom: PhantomData<T>,
}

An identifier for an arbitrary type T. This is a wrapper around usize which is bound to a type T.

Fields

index: Int

phantom: PhantomData<T>

Implementations

impl<T, Int: Copy> Index<T, Int>

pub(crate) fn new(index: Int) -> Self
