[−][src]Crate unique_type_id
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:
#[macro_use] extern crate unique_type_id_derive; extern crate unique_type_id; 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); }
