#
year_­month_­weekday_­last is a trivially copyable and standard-layout class type.
🔗
constexpr year_month_weekday_last(const chrono::year& y, const chrono::month& m, const chrono::weekday_last& wdl) noexcept;
2
#
Effects: Constructs an object of type year_­month_­weekday_­last by initializing y_­ with y, m_­ with m, and wdl_­ with wdl.
🔗
constexpr year_month_weekday_last& operator+=(const months& m) noexcept;
3
#
Effects: *this = *this + m.
4
#
Returns: *this.
🔗
constexpr year_month_weekday_last& operator-=(const months& m) noexcept;
5
#
Effects: *this = *this - m.
6
#
Returns: *this.
🔗
constexpr year_month_weekday_last& operator+=(const years& y) noexcept;
7
#
Effects: *this = *this + y.
8
#
Returns: *this.
🔗
constexpr year_month_weekday_last& operator-=(const years& y) noexcept;
9
#
Effects: *this = *this - y.
10
#
Returns: *this.
🔗
constexpr chrono::year year() const noexcept;
11
#
Returns: y_­.
🔗
constexpr chrono::month month() const noexcept;
12
#
Returns: m_­.
🔗
constexpr chrono::weekday weekday() const noexcept;
13
#
Returns: wdl_­.weekday().
🔗
constexpr chrono::weekday_last weekday_last() const noexcept;
14
#
Returns: wdl_­.
🔗
constexpr operator sys_days() const noexcept;
15
#
Returns: If ok() == true, returns a sys_­days that represents the last weekday() of year()/month().
Otherwise the returned value is unspecified.
🔗
explicit constexpr operator local_days() const noexcept;
16
#
Returns: local_­days{sys_­days{*this}.time_­since_­epoch()}.
🔗
constexpr bool ok() const noexcept;
17
#
Returns: y_­.ok() && m_­.ok() && wdl_­.ok().
