== Synopsis

Declared in `<bslstl_stringviewlikeparam.h>`

#define BSLSTL_STRINGVIEWLIKEPARAM_ONLY_ENABLE_IF_T(...)

== Description

Expand to an `enable_if` type alias for `ResultType` that is defined (i.e., SFINAE‐friendly) only when the `STRING_VIEW_LIKE_TYPE` template parameter is convertible to `bsl::basic_string_view<CHAR_TYPE, CHAR_TRAITS>` but is _not_ convertible to `const CHAR_TYPE *`. The `CHAR_TYPE` and `CHAR_TRAITS` template parameters must be in scope. The specified `ResultType` (passed as a variadic argument) is the resulting type when both conditions are satisfied.
