Id is a typed wrapper around a uuid::Uuid.
Use it to add type safety and prevent confusion between different kinds of Uuid.
Represent different types of Id to prevent mixups or invalid states. If describing
a unique resource's relationship to another, for example the Role a User has,
the relationship can be expressed as follows:
```rust
// Subtype the Id type to specify the version of the Id, instead
// of repeating yourself everywhere.
type Id
struct Relation {
user: Id
Ids with differentT` parameter types are incompatible, and cannot be compared.
Attempting to assign an Id<User> to a variable of type Id<Role> is a compilation error.
```rust
let user = Id::
// Compilation fails here, can't compare Id
But Ids of the same type work:
```rust
let mut first = Id::
first = second; assert_eq!(first, second); ```
When depending on this library, you need to explicitly select the versions of the uuid, you will be using, as well as optionally serde support:
toml
[dependencies.typed-uuid]
version = "*"
default-features = false
features = ["v4", "serde"]
