stateless_count_result
-
template<typename _Input>
class stateless_count_result The result of counting operations (such as ztd_text_count_as_encoded and ztd_text_count_as_encoded) that specifically do not include a reference to the state.
Subclassed by count_result< _Input, _State >, count_transcode_result< _Input, _FromState, _ToState >
Public Functions
-
template<typename _ArgInput>
inline constexpr stateless_count_result(_ArgInput &&__input, ::std::size_t __count, encoding_error __error_code = encoding_error::ok) Constructs a ztd::text::stateless_count_result, defaulting the error code to ztd::text::encoding_error::ok if not provided.
- Parameters
__input – [in] The input range to store.
__count – [in] The number of code points or code units successfully counted.
__error_code – [in] The error code for the encode operation, taken as the first of either the encode or decode operation that failed.
-
template<typename _ArgInput>
inline constexpr stateless_count_result(_ArgInput &&__input, ::std::size_t __count, encoding_error __error_code, ::std::size_t __error_count) Constructs a ztd::text::stateless_count_result with the provided parameters and information, including whether or not an error was handled.
- Parameters
__input – [in] The input range to store.
__count – [in] The number of code points or code units successfully counted.
__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
-
_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).
-
::std::size_t count
The number of code units or code points counted successfully, so far.
-
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.
Remark
This number may be greater than one despite
error_code
being ztd::text::encoding_error::ok, as some error handlers will encounter an error but “fix” the text (e.g. ztd::text::skip_handler_t or ztd::text::replacement_handler_t).
