Module cglue::result

FFI safe result.

This module contains several key parts:

CResult

It is a simple #[repr(C)] enum that is equivalent and interchangeable with Result.

IntError

IntError is a type that allows for efficient FFI-boundary crossing and simple interop with C code. It takes a Result<T, E>, and splits it up to 2 distinct parts

• ok_out pointer, and an integer return value. Value of zero always means success, and that ok_out was filled, whereas any other value can represent a specific meaning E must specify by itself.

IntResult

It is a helper trait that is implemented on all Result<T, E> types where E implements IntError.

Enums

CResult

FFI safe result.

Traits

IntError

Represents an integer-convertable error value.

IntResult

Helper trait for integer errors.

Functions

from_int_result^⚠

Convert from error code to concrete result.

from_int_result_empty

Convert from error code to Ok or Err.

into_int_out_result

Convert result into an integer error value, potentially writing the Ok value.

into_int_result

Convert result into an integer error value.
