stateless_decode_result

template<typename _Input, typename _Output>
class stateless_decode_result

The result of all decode operations from encoding objects and higher-level calls (such as ztd_text_decode).

Subclassed by decode_result< _Input, _Output, _State >

template<typename _ArgInput, typename _ArgOutput, ::std::enable_if_t<__txt_detail::__result_type_copy_constraint<::ztd::text::stateless_decode_result, _Input, _ArgInput, _Output, _ArgOutput>()>* = nullptr>

Constructs a ztd::text::decode_result with the provided parameters and information, including whether or not an error was handled.

Parameters

__other – [in] A different but related result type.

template<typename _ArgInput, typename _ArgOutput, ::std::enable_if_t<__txt_detail::__result_type_move_constraint<::ztd::text::stateless_decode_result, _Input, _ArgInput, _Output, _ArgOutput>()>* = nullptr>

Constructs a ztd::text::decode_result with the provided parameters and information, including whether or not an error was handled.

Parameters

__other – [in] A different but related result type.

template<typename _ArgInput, typename _ArgOutput, typename _ArgState>
inline constexpr stateless_decode_result(_ArgInput &&__input, _ArgOutput &&__output, encoding_error __error_code = encoding_error::ok) noexcept(noexcept(stateless_decode_result(::std::forward<_ArgInput>(__input), ::std::forward<_ArgOutput>(__output), __error_code, __error_code != encoding_error::ok)))

Constructs a ztd::text::decode_result, defaulting the error code to ztd::text::encoding_error::ok if not provided.

Parameters

• __input – [in] The input range to store.

• __output – [in] The output range to store.

• __error_code – [in] The error code for the decoding opertion, if any.

template<typename _ArgInput, typename _ArgOutput>
inline constexpr stateless_decode_result(_ArgInput &&__input, _ArgOutput &&__output, encoding_error __error_code, ::std::size_t __error_count) noexcept(::std::is_nothrow_constructible_v<_Input, _ArgInput> && ::std::is_nothrow_constructible_v<_Output, _ArgOutput>)

Constructs a ztd::text::decode_result with the provided parameters and information, including whether or not an error was handled.

Parameters

• __input – [in] The input range to store.

• __output – [in] The output range to store.

• __error_code – [in] The error code for the decode operation, taken as the first of either the decode operation that failed.

• __error_count – [in] Whether or not an error was handled. Some error handlers are corrective (see ztd::text::replacement_handler_t), and so the error code is not enough to determine if the handler was invoked. This allows the value to be provided directly when constructing this result type.

inline constexpr bool errors_were_handled() const noexcept

Whether or not any errors were handled.

Returns

Simply checks whether error_count is greater than 0.

Public Members

_Input input

The reconstructed input_view object, with its .begin() incremented by the number of code units successfully read (can be identical to .begin() on original range on failure).

_Output output

The reconstructed output_view object, with its .begin() incremented by the number of code units successfully written (can be identical to .begin() on original range on failure).

encoding_error error_code

The kind of error that occured, if any.

::std::size_t error_count

The number of times an error occurred in the processed input text.
