Trait jaffi_support::FromJavaValue

source · [−]

pub trait FromJavaValue<'j, J>: Sized {
    fn from_jvalue(env: JNIEnv<'j>, jvalue: JValue<'j>) -> Self;
}

Expand description

Convert from a JValue (return type in Java) into the Rust type

This is infallible because the generated code using it should “know” that the type is already correct

fn from_jvalue(env: JNIEnv<'j>, jvalue: JValue<'j>) -> Self
