Struct DownloadSpeed 

pub struct DownloadSpeed { /* private fields */ }

Download speed in bytes per second (fixed-point representation)

Internally stores bytes_per_second * SCALE for precision.

表示下载速度（单位：字节每秒，定点数表示）

内部存储 bytes_per_second * SCALE 以保持精度。

Implementations

impl DownloadSpeed

pub fn from_raw(bytes_per_second: u64) -> Self

Create a new download speed from raw bytes per second

Parameters

• bytes_per_second: Speed in bytes per second (can be zero)

从原始字节/秒创建一个新的下载速度实例

参数

• bytes_per_second: 字节/秒速度（可以为零）

pub fn new(bytes: u64, duration: Duration) -> Self

Create a new download speed from bytes downloaded and time taken

Uses pure integer arithmetic with nanosecond precision.

Parameters

• bytes: Number of bytes downloaded (can be zero)
• duration: Time taken for the download

从下载的字节数和所用时间创建一个新的下载速度实例

使用纯整数运算，保持纳秒级精度。

参数

• bytes: 下载的字节数（可以为零）
• duration: 下载所用的时间

pub fn as_scaled(&self) -> u128

Get the internal scaled value (for advanced usage)

获取内部缩放值（高级用途）

pub fn as_u64(&self) -> u64

Get the speed in bytes per second as u64 (floored)

以 u64 的形式获取字节每秒（向下取整）

pub fn as_f64(&self) -> f64

Get the speed as f64 (for compatibility)

以 f64 的形式获取速度（兼容用途）

impl Ord for DownloadSpeed

fn cmp(&self, other: &DownloadSpeed) -> 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,

impl PartialEq for DownloadSpeed

fn eq(&self, other: &DownloadSpeed) -> 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.

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
