Module robusta_jni::convert::safe

Fallible conversions traits.

These are the traits selected if call_type is omitted or if specified with a safe parameter.

#[call_type(safe)]

If any conversion fails, e.g. while converting input parameters or return arguments a Java exception is thrown. Exception class and exception message can be customized with the exception_class and message parameters of the safe option, as such:

#[call_type(safe(exception_class = "java.io.IOException", message = "Error while calling JNI function!"))]

Both of these parameters are optional. By default, the exception class is java.lang.RuntimeException.

Traits

• TryFromJavaValue
  Conversion trait from Java values to Rust values, analogous to TryFrom. Used when converting types that are input to JNI-available functions.
• TryIntoJavaValue
  Conversion trait from Rust values to Java values, analogous to TryInto. Used when converting types returned from JNI-available functions.
