This struct template implements a meta‐function to determine if the (template parameter) t_TYPE is convertible to bsl::basic_string_view<t_CHAR_TYPE, t_CHAR_TRAITS>.

Description

bsl::is_convertible<t_TYPE, bsl::basic_string_view<t_CHAR_TYPE, t_CHAR_TRAITS>>

This struct template implements the is_convertible meta‐function defined in the C++11 standard to determine whether the (template parameter) t_FROM_TYPE is implicitly convertible to the (template parameter) t_TO_TYPE.

Description

IsConvertibleToStringView<t_CHAR_TYPE, t_CHAR_TRAITS, t_CHAR_TYPE const(&)[>]

This partial specialization of IsConvertibleToStringView is instantiated when const t_CHAR_TYPE (&)[] (an unbounded array reference) is tested for convertibility to string view. This handles edge cases with certain compilers where bsl::is_convertible may not correctly handle incomplete array types.
