Alterando API
Vamos estender a API com mais funcionalidades: queremos permitir que os clientes especifiquem uma lista de frases para o cartĂŁo de aniversĂĄrio:
package com.example.birthdayservice;
/** Interface de serviço de aniversårio. */
interface IBirthdayService {
/** Gera uma mensagem de feliz aniversĂĄrio. */
String wishHappyBirthday(String name, int years, in String[] text);
}
This results in an updated trait definition for IBirthdayService
:
trait IBirthdayService {
fn wishHappyBirthday(
&self,
name: &str,
years: i32,
text: &[String],
) -> binder::Result<String>;
}
- Note how the
String[]
in the AIDL definition is translated as a&[String]
in Rust, i.e. that idiomatic Rust types are used in the generated bindings wherever possible:in
array arguments are translated to slices.out
andinout
args are translated to&mut Vec<T>
.- Return values are translated to returning a
Vec<T>
.
