서비스 구현

이제 AIDL서비스를 구현할 수 있습니다:

birthday_service/src/lib.rs:

//! `IBirthdayService` AIDL 인터페이스의 구현입니다.
use com_example_birthdayservice::aidl::com::example::birthdayservice::IBirthdayService::IBirthdayService;
use com_example_birthdayservice::binder;

/// `IBirthdayService` 구현입니다.
pub struct BirthdayService;

impl binder::Interface for BirthdayService {}

impl IBirthdayService for BirthdayService {
    fn wishHappyBirthday(&self, name: &str, years: i32) -> binder::Result<String> {
        Ok(format!(
            "Happy Birthday {name}, congratulations with the {years} years!"
        ))
    }
}

birthday_service/Android.bp:

rust_library {
    name: "libbirthdayservice",
    srcs: ["src/lib.rs"],
    crate_name: "birthdayservice",
    rustlibs: [
        "com.example.birthdayservice-rust",
        "libbinder_rs",
    ],
}
