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

inline constexpr pivotless_transcode_result(_ArgInput &&__input, _ArgOutput &&__output, _ArgFromState &&__from_state, _ArgToState &&__to_state, encoding_error __error_code = encoding_error::ok) Constructs a ztd::text::pivotless_transcode_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.
__from_state – [in] The state related to the “From Encoding” that performed the decode half of the operation.
__to_state – [in] The state related to the “To Encoding” that performed the encode half of the operation.
__error_code – [in] The error code for the transcoding operation, taken as the first of either the encode or decode operation that failed.

template<typename _ArgInput, typename _ArgOutput, typename _ArgFromState, typename _ArgToState>
inline constexpr pivotless_transcode_result(_ArgInput &&__input, _ArgOutput &&__output, _ArgFromState &&__from_state, _ArgToState &&__to_state, encoding_error __error_code, ::std::size_t __error_count) Constructs a ztd::text::pivotless_transcode_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.
__from_state – [in] The state related to the “From Encoding” that performed the decode half of the operation.
__to_state – [in] The state related to the “To Encoding” that performed the encode half of the operation.
__error_code – [in] The error code for the encode operation, taken as the first of either the encode or 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
-
::ztd::reference_wrapper<_FromState> from_state
A reference to the state of the associated Encoding used for decoding input code units to intermediate code points.
-
::ztd::reference_wrapper<_ToState> to_state
A reference to the state of the associated Encoding used for encoding intermediate code points to code units.
-
_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
Whether or not the error handler was invoked, regardless of if the error_code is set or not set to ztd::text::encoding_error::ok.
