Expand description
A unique id generator for rust types.
The crate provides a trait and a procedural macro. By deriving one, you implement the
trait with fn id() -> TypeId
static method. The type id is unique in the whole project.
For examples, see the tests
directory in the source tree.
§Usage
The example usage:
fn check_id() {
use unique_type_id::UniqueTypeId;
// This code uses "types.toml" (the default) file for ids.
#[derive(UniqueTypeId)]
struct Test1;
#[derive(UniqueTypeId)]
struct Test2;
assert_eq!(Test1::id().0, 1u64);
assert_eq!(Test2::id().0, 2u64);
}
