const_type
==========
Define `enum`-like `const`-types, but with aliases for variants:
```rust
use const_type::
{
Const,
};
Const!
{
/// `Bar` is like enum, but variants might have the same value.
/// `usize` is the default type, so `: usize` can be omitted in this case.
pub Bar: usize
{
/// Even Variants could be and should be documented.
A = 1,
B = 2,
C = 2,
D = Bar::A.0,
}
}
```
This could be used like this:
```rust
let Foo: Bar = Bar::B;
```
Because the `enum` is actually a `struct`, implementing `trait`s or methods canbe doneas usually:
```rust
impl Into < usize > for Bar
{
fn into
(
self
)
-> usize
{
self.0 as usize
}
}
```
