Translating Java method signatures to Rust
The java_package macro translates Java methods into Rust methods.
The method argument types are translated as follows:
| Java argument type | Rust argument type |
|---|---|
byte | impl duchess::IntoScalar<i8> |
short | impl duchess::IntoScalar<i16> |
int | impl duchess::IntoScalar<i32> |
long | impl duchess::IntoScalar<i64> |
| Java object type J | impl duchess::IntoJava<J> |
e.g., java.lang.String | impl duchess::IntoJava<java::lang::String> |
The Rust version of the Java method will return one of the following traits. These are not the actual Rust value, but rather the JVM operation that will yield the value when executed:
| Java return type | Rust return type |
|---|---|
void | impl duchess::VoidMethod |
byte | impl duchess::ScalarMethod<i8> |
| ... | impl duchess::ScalarMethod<...> |
long | impl duchess::ScalarMethod<i64> |
| Java object type J | impl duchess::JavaMethod<J> |
e.g., java.lang.String | impl duchess::JavaMethod<java::lang::String> |
