结构体 Written 

pub struct Written {
    pub bytes: usize,
    pub chunks: usize,
}

指示一次写入操作中已传输的字节数和块数

字段

bytes: usize

已写入的字节数

chunks: usize

已写入的完整数据块数量

如果某个数据块仅被部分写入，则不会被该字段计入。

trait 实现

impl Clone for Written

fn clone(&self) -> Written

返回值的副本。 更多信息

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

Performs copy-assignment from source. 更多信息

impl Debug for Written

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

使用给定的格式化器格式化此值。 更多信息

impl Default for Written

fn default() -> Written

Returns the “default value” for a type. 更多信息

impl PartialEq for Written

fn eq(&self, other: &Written) -> bool

测试 self 与 other 值是否相等，供 == 运算符使用。

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 Copy for Written

impl Eq for Written

impl StructuralPartialEq for Written
