Struct medea_client_api_proto::stats::HighResTimeStamp

pub struct HighResTimeStamp(pub f64);

Representation of DOMHighResTimeStamp.

Can be converted to the SystemTime with millisecond-wise accuracy.

HighResTimeStamp type is a f64 and is used to store a time value in milliseconds. This type can be used to describe a discrete point in time or a time interval (the difference in time between two discrete points in time).

The time, given in milliseconds, should be accurate to 5 µs (microseconds), with the fractional part of the number indicating fractions of a millisecond. However, if the browser is unable to provide a time value accurate to 5 µs (due, for example, to hardware or software constraints), the browser can represent the value as a time in milliseconds accurate to a millisecond. Also note the section below on reduced time precision controlled by browser preferences to avoid timing attacks and fingerprinting.

Further, if the device or operating system the user agent is running on doesn't have a clock accurate to the microsecond level, they may only be accurate to the millisecond.

Trait Implementations

impl Clone for HighResTimeStamp

fn clone(&self) -> HighResTimeStamp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for HighResTimeStamp

impl Debug for HighResTimeStamp

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HighResTimeStamp

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl From<SystemTime> for HighResTimeStamp

fn from(time: SystemTime) -> Self

Performs the conversion.

impl Hash for HighResTimeStamp

Hashing string representation.

Some people believe that such behavior is incorrect (but in some programming languages this is a default behavior) due to NaN, Inf or -Inf (they all will have the same hashes). But in the case of RtcStat received from the client, there should be no such situations, and the hash will always be correct.

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl PartialEq<HighResTimeStamp> for HighResTimeStamp

Comparison string representations.

Such implementation is required, so that the results of comparing values and comparing hashes match.

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Serialize for HighResTimeStamp

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
