// This test doesn't run any code, the fact that it compiles is the actual testing.
// It checks that the derive macro generation is immune to type shadowing,
// i.e. any types that are in scope and happen to have the same name as elrond-codec types do not break the build.
// The derive macro must generate fully qualified type names everywhere to avoid this hurdle.

// All exported traits:
struct TopEncode;
struct TopDecode;
struct NestedEncode;
struct NestedDecode;
struct EncodeError;
struct DecodeError;
struct TopDecodeInput;
struct TopEncodeOutput;
struct NestedDecodeInput;
struct NestedEncodeOutput;

// Making sure derive explicitly only works with core::result::Result
// and doesn't get tricked by other enums with the same name.
enum Result {
    Ok,
    Err,
}

// This one will interfere with any improperly generated `Ok` and `Err` expressions.
#[allow(unused_imports)]
use crate::Result::{Err, Ok};

// Also adding all public functions exposed by elrond-codec.
// They are not used in the derive, but just to make sure:
