validate_transcode_result

template<typename _Input, typename _DecodeState, typename _EncodeState, typename _Pivot>
class validate_transcode_result : public ztd::text::validate_pivotless_transcode_result<_Input, _DecodeState, _EncodeState>

The result of a transcoding validation operations (e.g. from ztd_text_validate_transcodable_as).

Public Functions

template<typename _ArgInput, typename _ArgFromState, typename _ArgToState, typename _ArgPivot>
inline constexpr validate_transcode_result(_ArgInput &&__input, bool __is_valid, _ArgFromState &&__from_state, _ArgToState &&__to_state, _ArgPivot &&__pivot)

Constructs a ztd::text::pivot_validate_result.

Parameters

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

• __is_valid – [in] Whether or not the validation succeeded.

• __from_state – [in] The state related to the encoding that was used to do validation.

• __to_state – [in] The state related to the encoding that was used to do validation.

• __pivot – [in] The pivot range to store.

inline explicit constexpr operator bool() const noexcept

A conversion for use in if statements and conditional operators.

Returns

Whether or not the result is valid or not.

Public Members

_Pivot pivot

The range used to hold the intermediate pivot transcoding units.

::ztd::reference_wrapper<_DecodeState> from_state

A reference to the state of the associated Encoding used for validating the input.

::ztd::reference_wrapper<_EncodeState> to_state

A reference to the state of the associated Encoding used for validating the input.

_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).

bool valid

Whether or not the specified input is valid or not.
