Enum 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

last_marked: DateTime<Utc>

The time when the timer was last marked.

Implementations

impl Timer

pub fn new() -> Self

Creates a new timer.

pub 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.

pub fn mark_millis(&mut self) -> u64

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

pub 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 Clone for Timer

fn clone(&self) -> Timer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Timer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Timer

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

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Timer

fn cmp(&self, other: &Timer) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Timer

fn eq(&self, other: &Timer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Timer

fn partial_cmp(&self, other: &Timer) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
