Purpose:

Provide metafunction to identify no-throw move-constructible types.

Classes:

bsl::is_nothrow_move_constructible	type-traits metafunction
bsl::is_nothrow_move_constructible_v	the metafunction's result value

Description:

This component defines a metafunction, bsl::is_nothrow_move_constructible, and a variable template bsl::is_nothrow_move_constructible_v that represents the result value of the bsl::is_nothrow_move_constructible metafunction, which may be used to query whether a type has a constructor that can be called with a single rvalue that is known to not throw exceptions. Note that a C++11 compiler will automatically infer this trait for class types with a move constructor that is marked as noexcept.

bsl::is_nothrow_move_constructible meets the requirements of the is_nothrow_move_constructible template defined in the C++11 standard.

Note that the template variable is_nothrow_move_constructible_v is defined in the C++17 standard as an inline variable. If the current compiler supports the inline variable C++17 compiler feature, bsl::is_nothrow_move_constructible_v is defined as an 'inline constexpr bool' variable. Otherwise, if the compiler supports the variable templates C++14 compiler feature, bsl::is_nothrow_move_constructible_v is defined as a non-inline constexpr bool variable. See BSLS_COMPILERFEATURES_SUPPORT_INLINE_VARIABLES and BSLS_COMPILERFEATURES_SUPPORT_VARIABLE_TEMPLATES macros in the bsls_compilerfeatures component for details.
