Array Types
The array types (T[], byte[], and List<T>) get translated to the
appropriate Rust array type depending on how they are used in the function
signature:
| Position | Rust Type |
|---|---|
in argument | &[T] |
out/inout argument | &mut Vec<T> |
| Return | Vec<T> |
- In Android 13 or higher, fixed-size arrays are supported, i.e.
T[N]becomes[T; N]. Fixed-size arrays can have multiple dimensions (e.g.int[3][4]). In the Java backend, fixed-size arrays are represented as array types. - Arrays in parcelable fields always get translated to
Vec<T>.
