Struct FileSize 

pub struct FileSize { /* private fields */ }

A non-zero file size representation

Type Parameters

• USE_SI:
  • true: Use SI standard (base-1000, units: KB, MB)
  • false: Use IEC standard (base-1024, units: KiB, MiB)

一个表示非零文件大小的结构体。

泛型

• USE_SI:
  • true: 使用 SI 标准 (base-1000, 单位 KB, MB)
  • false: 使用 IEC 标准 (base-1024, 单位 KiB, MiB)

Implementations

impl FileSize

pub fn new(bytes: NonZeroU64, standard: SizeStandard) -> Self

Create a new FileSize instance

创建一个新的 FileSize 实例

pub fn get_nonzero(&self) -> NonZeroU64

Get the inner NonZeroU64 byte value

获取内部的 NonZeroU64 字节值

pub fn as_u64(&self) -> u64

Get the byte value as u64

以 u64 的形式获取字节值

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

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

The formatted_value is returned as String to ensure correct decimal places (e.g., “1.00”)

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

formatted_value 作为 String 返回，以保证正确的小数位数 (例如 “1.00”)

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

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

The formatted_value is returned as String to ensure correct decimal places (e.g., “1.00”)

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

formatted_value 作为 String 返回，以保证正确的小数位数 (例如 “1.00”)

Trait Implementations

impl Clone for FileSize

fn clone(&self) -> FileSize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileSize

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

Formats the value using the given formatter.

impl Display for FileSize

Implement Display trait for smart formatting

实现 Display trait 来处理智能格式化

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

Formats the value using the given formatter.

impl PartialEq for FileSize

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 FileSize

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.
