Struct FileSize 

pub struct FileSize { /* private fields */ }

A file size representation that can be zero

一个可以表示零的文件大小结构体。

Implementations

impl FileSize

pub const fn new(bytes: u64) -> Self

Create a new FileSize instance from bytes

从字节数创建一个新的 FileSize 实例

pub const fn as_u64(&self) -> u64

Get the byte value as u64

以 u64 的形式获取字节值

pub fn to_nonzero(&self) -> Option<NonZeroFileSize>

Convert to NonZeroFileSize if the value is not zero

如果值不为零，则转换为 NonZeroFileSize

impl From<NonZeroFileSize> for FileSize

fn from(size: NonZeroFileSize) -> Self

Converts to this type from the input type.

impl From<u64> for FileSize

fn from(bytes: u64) -> Self

Converts to this type from the input type.

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 FileSize

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