陣列

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:

PositionRust 型別
in argument&[T]
out/inout argument&mut Vec<T>
ReturnVec<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>.
