Trait robusta_jni::convert::Signature

pub trait Signature {
    const SIG_TYPE: &'static str;
}

This trait provides type signatures for types. It is necessary to support conversions to/from Java types.

While you can implement this trait manually, you should probably use the derive macro.

The derive macro requires a #[package()] attribute on implementing structs (most likely you already have that).

Required Associated Constants

const SIG_TYPE: &'static str

Java type signature for the implementing type.

Object Safety

This trait is not object safe.
