Struct DownloadAcceleration 

pub struct DownloadAcceleration { /* private fields */ }

Download acceleration in bytes per second squared

下载加速度（单位：字节每秒平方）

Implementations

impl DownloadAcceleration

pub fn from_raw(bytes_per_second_sq: i64, standard: SizeStandard) -> Self

Create a new download acceleration from raw bytes per second squared

Parameters

• bytes_per_second_sq: Non-zero acceleration in bytes per second squared
• standard: Standard to use (SI or IEC)

Note

For negative acceleration, use as u64 conversion of i64 to ensure proper sign handling

从原始字节/秒²创建一个新的下载加速度实例

参数

• bytes_per_second_sq: 非零的字节/秒²加速度值
• standard: 使用的标准（SI 或 IEC）

注意

对于负加速度，使用 i64 的 as u64 转换，确保正确处理符号位

pub fn new( initial_speed: NonZeroU64, final_speed: NonZeroU64, duration: Duration, standard: SizeStandard, ) -> Self

Create a new download acceleration from speed change and time interval

Parameters

• initial_speed: Initial speed in non-zero bytes per second
• final_speed: Final speed in non-zero bytes per second
• duration: Time interval for the speed change
• standard: Standard to use (SI or IEC)

Panics

Panics if initial_speed or final_speed is zero

从下载速度变化量和时间间隔创建一个新的下载加速度实例

参数

• initial_speed: 初始速度（非零字节/秒）
• final_speed: 最终速度（非零字节/秒）
• duration: 速度变化所用的时间
• standard: 使用的标准（SI 或 IEC）

Panics

如果 initial_speed 或 final_speed 为零，此函数会 panic。

pub fn as_decimal(&self) -> Decimal

Get the acceleration in bytes per second squared as a Decimal

以 Decimal 的形式获取字节每秒平方

pub fn as_i64(&self) -> i64

Get the acceleration in bytes per second squared as i64 (floored)

以 i64 的形式获取字节每秒平方（向下取整）

pub fn get_si_parts(&self) -> (String, &'static str)

Returns the formatted value and unit in SI (base-1000) standard

返回 SI (base-1000) 标准的 (formatted_value, unit)

pub fn get_iec_parts(&self) -> (String, &'static str)

Returns the formatted value and unit in IEC (base-1024) standard

返回 IEC (base-1024) 标准的 (formatted_value, unit)

Trait Implementations

impl Clone for DownloadAcceleration

fn clone(&self) -> DownloadAcceleration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DownloadAcceleration

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

Formats the value using the given formatter.

impl Display for DownloadAcceleration

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

Formats the value using the given formatter.

impl PartialEq for DownloadAcceleration

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

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.
