Classes
class	bsl::is_nothrow_convertible< From, To >
	If the provided type is convertible from "From" to "To", provides the member constant value equal to true. Otherwise the member constant value is false. More...

Functions
template<typename T >
auto	bsl::details::test_is_nothrow_convertible1 (bsl::int32 ignored) noexcept -> true_type_for< T()>
	Tests if the provided type is returnable, which is required for a type to be convertible. If the type is returnable, this returns true, false otherwise. More...
template<typename T >
auto	bsl::details::test_is_nothrow_convertible1 (bool ignored) noexcept -> false_type
	Tests if the provided type is returnable, which is required for a type to be convertible. If the type is returnable, this returns true, false otherwise. More...
template<typename From , typename To >
auto	bsl::details::test_is_nothrow_convertible2 (bsl::int32 ignored) noexcept -> bool_constant< noexcept(declval< void(&)(To) noexcept >()(declval< From >()))>
	Tests whether or not the provided to can be converted from "From" to "To" via a function parameter similar to an implicit conversion constructor (but might be implicitly provided by the compiler). If the type is convertible, this returns true, false otherwise. More...

Function Documentation

test_is_nothrow_convertible1() [1/2]

template<typename T >

auto bsl::details::test_is_nothrow_convertible1 ( bsl::int32  ignored ) -> true_type_for< T()>

noexcept

Tests if the provided type is returnable, which is required for a type to be convertible. If the type is returnable, this returns true, false otherwise.

Template Parameters

T	The type to query

Parameters

ignored

(only used for overload resolution)

Returns

returns true if T is returnable, false otherwise

test_is_nothrow_convertible1() [2/2]

template<typename T >

auto bsl::details::test_is_nothrow_convertible1 ( bool  ignored ) -> false_type

noexcept

Tests if the provided type is returnable, which is required for a type to be convertible. If the type is returnable, this returns true, false otherwise.

Template Parameters

T	The type to query

Parameters

ignored

(only used for overload resolution)

Returns

returns true if T is returnable, false otherwise

test_is_nothrow_convertible2() [1/2]

template<typename From , typename To >

auto bsl::details::test_is_nothrow_convertible2 ( bsl::int32  ignored ) -> bool_constant< noexcept(declval< void(&)(To) noexcept >()(declval< From >()))>

noexcept

Tests whether or not the provided to can be converted from "From" to "To" via a function parameter similar to an implicit conversion constructor (but might be implicitly provided by the compiler). If the type is convertible, this returns true, false otherwise.

Template Parameters

From	the type to convert to
To	the type to convert from

Parameters

ignored

(only used for overload resolution)

Returns

returns true if T is returnable, false otherwise

test_is_nothrow_convertible2() [2/2]

template<typename From , typename To >

auto bsl::details::test_is_nothrow_convertible2 ( bool  ignored ) -> false_type

noexcept

Tests whether or not the provided to can be converted from "From" to "To" via a function parameter similar to an implicit conversion constructor (but might be implicitly provided by the compiler). If the type is convertible, this returns true, false otherwise.

Template Parameters

From	the type to convert to
To	the type to convert from

Parameters

ignored

(only used for overload resolution)

Returns

returns true if T is returnable, false otherwise

check_is_nothrow_convertible()

template<typename From , typename To >

constexpr bool bsl::details::check_is_nothrow_convertible ( )

noexcept

Performs all of the tests including testing if both types are void.

Template Parameters

From	the type to convert to
To	the type to convert from

Returns

returns true if T is returnable, false otherwise
