Rust Libraries

You use rust_library to create a new Rust library for Android.

Here we declare a dependency on two libraries:

• libgreeting, which we define below,
• libtextwrap, which is a crate already vendored in external/rust/crates/.

hello_rust/Android.bp:

{{#include library/Android.bp}}

hello_rust/src/main.rs:

{{#include library/src/main.rs:main}}

hello_rust/src/lib.rs:

{{#include library/src/lib.rs:greeting}}

You build, push, and run the binary like before:

{{#include ../build_all.sh:hello_rust_with_dep}}
Hello Bob, it is very
nice to meet you!
