枚举 EcnCodepoint 

#[repr(u8)]
pub enum EcnCodepoint {
    Ect0 = 2,
    Ect1 = 1,
    Ce = 3,
}

显式拥塞通知 (ECN) 码点

变体

Ect0 = 2

ECT(0) 码点，表示端点具备 ECN 能力

Ect1 = 1

ECT(1) 码点，表示端点具备 ECN 能力

Ce = 3

CE 码点，表示已发生拥塞

实现

impl EcnCodepoint

pub fn from_bits(x: u8) -> Option<EcnCodepoint>

由给定的位创建一个新对象

pub fn is_ce(self) -> bool

返回该码点是否为 CE，即是否已发生拥塞

trait 实现

impl Clone for EcnCodepoint

fn clone(&self) -> EcnCodepoint

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 EcnCodepoint

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 PartialEq for EcnCodepoint

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