Public Types
using	Clock = std::chrono::steady_clock
	Clock used by the timer, monotonic with nanosecond resolution.

Public Member Functions
	Timer ()
	Creates a timer that starts measuring right away.
void	Reset ()
	Resets the timer to zero.
double	ElapsedSeconds () const
	Returns the time elapsed since the timer was created or last reset, in seconds.
double	ElapsedMilliseconds () const
	Returns the time elapsed since the timer was created or last reset, in milliseconds.

Detailed Description

High-resolution (steady) timer that measures the time elapsed since it was created or last reset.

It relies on a monotonic clock, so changes to the system time do not affect it.

Timer timer; LoadScene(); double ms = timer.ElapsedMilliseconds();

Member Typedef Documentation

Clock

using Quasar::Timer::Clock = std::chrono::steady_clock

Clock used by the timer, monotonic with nanosecond resolution.

std::chrono::high_resolution_clock is not used on purpose: it is an alias whose target depends on the standard library, and with libstdc++ it is the system clock, which is not monotonic.
