Detailed Description

template<typename... T>
class sumty::make_error_set< T >

Utility to create an error_set type.

make_error_set is a builder for the error_set type that deduplicates alternatives. error_set requires that each alternative be a unique type, so make_error_set simplifies generically building an error_set by ensuring that condition is met automatically.

Example

assert(is_equivalent_v<
    typename make_error_set<
        error1, error2, error1, error1, error3, error2
    >::type,
    error_set<error1, error2, error3>
>);

Template Parameters

T	The alternative types of the resulting error_set
