Public Member Functions
std::string	to_string () const override
	Render the cell's value as a compact human-readable string.
json_t	to_json () const override
	Default JSON serialization for cells with JSON-convertible storage.
Public Member Functions inherited from parcel::BaseCell< SystemTimePointCell, std::chrono::sys_seconds >
	explicit (false) BaseCell(U &&v)
	Construct by forwarding into the storage (v becomes Storage::value).
SystemTimePointCell &	operator= (U &&v)
	Assign to the storage from v.
std::chrono::sys_seconds &	get ()
	Mutable access to the held storage.
std::chrono::sys_seconds const &	get () const
	Read-only access to the held storage.
std::partial_ordering	compare (ICell const &other) const override
	Default three-way comparison: kind first, then storage value.
void	inject_display_info (json_t &j) const
	Copy this cell's display info (if any) into the JSON object under "d".
Public Member Functions inherited from parcel::ICell
virtual std::string	to_formatted_string () const
	Render the cell as a multi-line, indented string.
virtual std::size_t	hash_value () const noexcept
	Equality-consistent hash that mirrors compare's display-info-insensitivity.
cell_t	with_display_info (DisplayInfo m) const
	Return a deep copy with the entire display info block replaced.
cell_t	with_name (std::string v) const
	Return a deep copy with name set to v.
cell_t	with_description (std::string v) const
	Return a deep copy with description set to v.
cell_t	with_icon (comms::Icon icon) const
	Return a deep copy with icon set to the typed icon.
cell_t	with_icon (std::string const &v) const
	Return a deep copy with icon parsed from an Iconify set:name string (e.g.
cell_t	with_color (comms::Color color) const
	Return a deep copy with color set to the typed color.
cell_t	with_color (std::string const &v) const
	Return a deep copy with color parsed from a color string (hex like "#ffcc00", a CSS-functional form, or a CSS color name).

Detailed Description

Wall-clock time at second resolution (ISO-8601-friendly).

Wire kind: "time:sys_seconds". Value is i64 epoch seconds — no string round-trip on the hot path.

Member Function Documentation

to_json()

json_t parcel::SystemTimePointCell::to_json ( ) const

inlineoverridevirtual

Default JSON serialization for cells with JSON-convertible storage.

If Storage has a JSON adapter, emits {"k": kind_id, "v": value, optional "d": display info}. Otherwise the call throws — the derived cell must override to_json itself (ListCell, MapCell, etc.).

Returns

JSON object representation.

Exceptions

std::runtime_error

if Storage is not JSON-convertible.

Reimplemented from parcel::BaseCell< SystemTimePointCell, std::chrono::sys_seconds >.

to_string()

std::string parcel::SystemTimePointCell::to_string ( ) const

inlineoverridevirtual

Render the cell's value as a compact human-readable string.

Returns

String form — implementation-defined per cell type.

Implements parcel::ICell.
