Public functions

void clear_error() constexpr noexcept

Clears the error state.

auto error() const -> bool constexpr noexcept

Returns true if the decoder has entered an error state.

auto has_value() const -> bool constexpr noexcept

Returns true if the decoder has a decoded a full UTF-32 codepoint.

auto needs_more_input() const -> bool constexpr noexcept

Returns true if the decoder needs more input before it can yield a UTF-32 codepoint.

void operator()(uint16_t code_unit) constexpr noexcept

Appends a UTF-16 code unit to the stream being decoded.

void operator()(char16_t code_unit) constexpr noexcept

Appends a UTF-16 code unit to the stream being decoded.

auto value() const -> char32_t constexpr noexcept

Returns the currently-decoded UTF-32 codepoint.
