Trait IntoJava

pub trait IntoJava<'borrow, 'env: 'borrow> {
    type JavaType: AsJValue<'env>;

    const JNI_SIGNATURE: &'static str;

    // Required method
    fn into_java(self, env: &'borrow JnixEnv<'env>) -> Self::JavaType;

    // Provided method
    fn jni_signature(&self) -> &'static str { ... }
}

Conversion from a type into its Java representation.

A type that implements this trait has an equivalent Java representation.

Required Associated Constants

const JNI_SIGNATURE: &'static str

The JNI signature of the Java type.

Required Associated Types

type JavaType: AsJValue<'env>

The Rust type that wraps a reference to the Java type.

Required Methods

fn into_java(self, env: &'borrow JnixEnv<'env>) -> Self::JavaType

Performs the conversion.

Provided Methods

fn jni_signature(&self) -> &'static str

Returns the JNI signature of the Java type.

This is a helper method to obtain the JNI_SIGNATURE from a value without knowing its exact type name.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
