Enum delta::Timer

pub enum Timer {
    NotStarted,
    Started {
        last_marked: DateTime<Utc>,
    },
}

A timer.

Variants

NotStarted

The timer has not been started yet.

Started

The timer has been started.

Fields of Started

last_marked: DateTime<Utc>

The time when the timer was last marked.

Methods

impl Timer

fn new() -> Self

Creates a new timer.

fn mark(&mut self) -> Duration

Marks a new instant, returning the number of seconds since the last mark.

The very first mark will return a delta time of 0.0. Because of this, any time between timer creation and the first mark will have no affect on the delta times returned.

fn mark_millis(&mut self) -> u64

Marks a new instant, returning the number of milliseconds since the last mark.

fn mark_secs(&mut self) -> f64

Marks a new instant, returning the number of seconds since the last mark.

The value returned is fractional - if 1 millisecond has passed, then 0.001 will be returned.

Trait Implementations

impl Copy for Timer

impl Clone for Timer

fn clone(&self) -> Timer

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

impl Hash for Timer

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)
