Struct libdata::flow::Speed

pub struct Speed(pub u64);

A transfer speed.

This specifies the speed of transfer in bytes per second, rounded to whole bytes per second.

Methods

impl Speed

fn compute(bytes: Bytes, time: Duration) -> Self

Computes the speed from the amount of data transfered and time it took.

This computes the speed simply as bytes / time. However, it shields the caller from bunch of technical details, like type conversions, the right units, rounding...

Note

The time is taken as one second long if it is shorter. This is to prevent various strange things from happening, like:

• Division by zero.
• Producing strange spikes for single-packet or very short flows (eg. it is possible to send several packets into a buffer in a very short time without the network having that actual speed).

Parameters

• bytes: The amount of bytes transferred.
• time: How long it took.

impl Ord for Speed

fn cmp(&self, __arg_0: &Speed) -> Ordering

This method returns an Ordering between self and other.

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

🔬 This is a nightly-only experimental API. (ord_max_min)

Compares and returns the maximum of two values.

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

🔬 This is a nightly-only experimental API. (ord_max_min)
