Module interoptopus::patterns::result

For return enums with defined Ok variants; may translate to exceptions if not met.

Examples

Functions returning a FFIError might receive special treatment in backends supporting exception handling. For example, a service method defined as:

pub fn my_method() -> Result<(), Error> {
    Ok(())
}

might receive a binding helper equivalent to:

public void MyMethod()
{
    var rval = Interop.simple_service_my_method(_context);
    if (rval != FFIError.Ok)
    {
        throw new Exception($"Something went wrong {rval}");
    }
}

Structs

FFIErrorEnum

Internal helper derived for enums that are an FFIError.

Traits

FFIError

A trait you should implement for enums that signal errors in FFI calls.

Functions

panics_and_errors_to_ffi_enum

Helper to transform Result types to FFIError::SUCCESS enums inside extern "C" functions.
