Type Alias FFIResult 

pub type FFIResult<T> = Result<T, ErrorCode>;

A result from an FFI function.

Because FFI functions cannot return multiple values, the actual type returned from an FFI function will be just the error code. The actual value that would be returned if the function was successful will be pulled from an output argument that was passed to the extern function

Aliased Type

pub enum FFIResult<T> {
    Ok(T),
    Err(ErrorCode),
}

Variants

Ok(T)
