Enum ClockSkew 

pub enum ClockSkew {
    Slow(Duration),
    None,
    Fast(Duration),
}

A reported amount of clock skew from a relay or other source.

Note that this information may not be accurate or trustworthy: the relay could be wrong, or lying.

The skews reported here are minimum amounts; the actual skew may be a little higher, depending on latency.

Variants

Slow(Duration)

Our own clock is “running slow”: the relay’s clock is at least this far ahead of ours.

None

Our own clock is not necessarily inconsistent with the relay’s clock.

Fast(Duration)

Own own clock is “running fast”: the relay’s clock is at least this far behind ours.

Implementations

impl ClockSkew

pub fn magnitude(&self) -> Duration

Return the magnitude of this clock skew.

pub fn as_secs_f64(&self) -> f64

Return this clock skew as a signed number of seconds, with slow values treated as negative and fast values treated as positive.

pub fn from_secs_f64(seconds: f64) -> Option<Self>

Return a clock skew computed from a signed number of seconds.

Returns None if the value is degenerate.

pub fn if_above(self, min: Duration) -> Self

Return this value if it is greater than min; otherwise return None.

pub fn is_skewed(&self) -> bool

Return true if we’re estimating any skew.

Trait Implementations

impl Clone for ClockSkew

fn clone(&self) -> ClockSkew

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClockSkew

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

Formats the value using the given formatter.

impl Ord for ClockSkew

fn cmp(&self, other: &Self) -> 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 ClockSkew

fn eq(&self, other: &ClockSkew) -> 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 ClockSkew

fn partial_cmp(&self, other: &Self) -> 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.
