Struct `core.time.TickDuration`

Warning: TickDuration will be deprecated in the near future (once all uses of it in Phobos have been deprecated). Please use MonoTime for the cases where a monotonic timestamp is needed and Duration when a duration is needed, rather than using TickDuration. It has been decided that TickDuration is too confusing (e.g. it conflates a monotonic timestamp and a duration in monotonic clock ticks) and that having multiple duration types is too awkward and confusing.


						
				struct TickDuration
				;

Represents a duration of time in system clock ticks.

The system clock ticks are the ticks of the system clock at the highest precision that the system provides.

Constructors

Name	Description
`this`

Fields

Name	Type	Description
`appOrigin`	`immutable(TickDuration)`	The tick of the system clock (as a `TickDuration`) when the application started.
`length`	`long`	The number of system ticks in this `TickDuration`.
`ticksPerSec`	`immutable(long)`	The number of ticks that the system clock has in one second.

Properties

Name	Type	Description
`currSystemTick`[get]	`TickDuration`	The current system tick. The number of ticks per second varies from system to system. `currSystemTick` uses a monotonic clock, so it's intended for precision timing by comparing relative time values, not for getting the current system time.
`hnsecs`[get]	`long`	Returns the total number of hecto-nanoseconds in this `TickDuration`.
`max`[get]	`TickDuration`	Largest `TickDuration` possible.
`min`[get]	`TickDuration`	Most negative `TickDuration` possible.
`msecs`[get]	`long`	Returns the total number of milliseconds in this `TickDuration`.
`nsecs`[get]	`long`	Returns the total number of nanoseconds in this `TickDuration`.
`seconds`[get]	`long`	Returns the total number of seconds in this `TickDuration`.
`usecs`[get]	`long`	Returns the total number of microseconds in this `TickDuration`.
`zero`[get]	`TickDuration`	It's the same as `TickDuration(0)`, but it's provided to be consistent with `Duration` and `FracSec`, which provide `zero` properties.

Methods

Name	Description
`from`	This allows you to construct a `TickDuration` from the given time units with the given length.
`opBinary`	Adds or subtracts two `TickDuration`s.
`opBinary`	The legal types of arithmetic for `TickDuration` using this operator overload are
`opBinary`	The legal types of arithmetic for `TickDuration` using this operator overload are
`opCast`	Returns a `Duration` with the same number of hnsecs as this `TickDuration`. Note that the conventional way to convert between `TickDuration` and `Duration` is using `to`, e.g.: `tickDuration.to!Duration()`
`opCmp`	operator overloading "<, >, <=, >="
`opOpAssign`	Adds or subtracts two `TickDuration`s as well as assigning the result to this `TickDuration`.
`opOpAssign`	The legal types of arithmetic for `TickDuration` using this operator overload are
`opOpAssign`	The legal types of arithmetic for `TickDuration` using this operator overload are
`opUnary`	Returns the negation of this `TickDuration`.
