Re-exports

pub use self::string::from_c_str;

pub use self::string::StringError;

bindgen_utils	Utilities for binding generators.
callback	Helpers to work with extern "C" callbacks.
java	Java/JNI utilities.
string	Utilities for passing strings across FFI boundaries.
test_utils	Test utilities.

call_result_cb
ffi_error	Converts a result into a pair of `(error_code: i32, description: CString)` to be used in `FfiResult`
ffi_error_code
ffi_result	Converts a result into a pair of `(error_code: i32, description: CString)` to be used in `FfiResult`
ffi_result_code
gen_byte_array_converter
gen_ctx	Generates a `user_data` context containing a reference to a single or several Java callbacks
gen_object_array_converter
gen_primitive_type_converter	Generates primitive type converters
jni_unwrap	Unwraps the results and checks for Java exceptions. Required for exceptions pass-through (simplifies debugging).
try_cb

FfiResult	FFI result wrapper
OpaqueCtx	Type that holds opaque user data handed into FFI functions

Constant value to be used for OK result

ErrorCode	Trait for types that can be converted to integer error code.
ReprC	Trait to convert between FFI and Rust representations of types
SafePtr	Provides FFI-safe pointers, as opposed to raw `as_ptr()` in `Vec` and `String` which can return values such as `0x01` that can cause segmentation faults with the automatic pointer dereferencing on the front-end side (e.g. in Node.js).

base64_decode	Decode base64 encoded data.
base64_encode	Encode the data using base64 encoding.
catch_unwind_cb	Catch panics. On error call the callback.
vec_clone_from_raw_parts ^⚠	Converts a pointer and lengts to Vec by cloning the contents.
vec_into_raw_parts	Converts a Vec to (pointer, size, capacity)
