Rust 程式庫

您可以使用 rust_library 為 Android 建立一個新的 Rust 程式庫。

這裡,我們會宣告兩個需要依附的程式庫:

hello_rust/Android.bp

rust_binary { name: "hello_rust_with_dep", crate_name: "hello_rust_with_dep", srcs: ["src/main.rs"], rustlibs: [ "libgreetings", "libtextwrap", ], prefer_rlib: true, // Need this to avoid dynamic link error. } rust_library { name: "libgreetings", crate_name: "greetings", srcs: ["src/lib.rs"], }

hello_rust/src/main.rs

//! Rust demo. use greetings::greeting; use textwrap::fill; /// Prints a greeting to standard output. fn main() { println!("{}", fill(&greeting("Bob"), 24)); }

hello_rust/src/lib.rs

//! Greeting library. /// Greet `name`. pub fn greeting(name: &str) -> String { format!("Hello {name}, it is very nice to meet you!") }

請按照之前的方式,建構、推送及執行二進位檔:

m hello_rust_with_dep adb push "$ANDROID_PRODUCT_OUT/system/bin/hello_rust_with_dep" /data/local/tmp adb shell /data/local/tmp/hello_rust_with_dep
Hello Bob, it is very nice to meet you!
