Support Result<T, E> type in typegen

[spacedragon]

What version of fuels-ts are you using?

latest

Steps to Reproduce

Expected Behavior

The correct code is

export type ResultInput<T,E> = Enum<{ Ok: T, Err: E }>;
export type ResultOutput<T,E>=  ResultInput<T,E>;

Actual Behavior

export type ResultInput = Enum<{ Ok: T, Err: E }>;
export type ResultOutput=  ResultInput;

@spacedragon I realized now that I misread the error you reported here. What you reported indeed seems off. Can you share the ABI which led to this problem?

Made some small changes to the counter example from the starter guide, following is the sway code

contract;

pub struct Foo {
    bar: u64,
    baz: bool
}

enum ColorError {
    Blue: (),
    Green: (),
    Red: (),
    Other: (),
}

storage {
    counter: u64 = 0,
    foo: Foo= Foo {
        bar: 0,
        baz: false
    },
}

abi Counter {
    #[storage(read, write)]
    fn increment(add: u32, two: u64, three: b256) -> u64;

    #[storage(read)]
    fn count() -> u64;

    #[storage(read, write)]
    fn complex(foo: Foo, option: Option<str[1]>) -> Result<Foo, ColorError>;
}

@spacedragon Thanks for the report and the ABI, it is indeed an issue.
