枚举 Side 

pub enum Side {
    Client = 0,
    Server = 1,
}

端点是连接的发起方还是接收方

变体

Client = 0

连接的发起方

Server = 1

连接的接受方

实现

impl Side

pub fn is_client(self) -> bool

等价于 self == Side::Client

pub fn is_server(self) -> bool

即 self == Side::Server 的简写

trait 实现

impl Clone for Side

fn clone(&self) -> Side

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 Side

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 Hash for Side

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher. 更多信息

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher. 更多信息

impl Not for Side

type Output = Side

应用 ! 运算符后得到的类型。

fn not(self) -> Side

Performs the unary ! operation. 更多信息

impl Ord for Side

fn cmp(&self, other: &Side) -> Ordering

This method returns an Ordering between self and other. 更多信息

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values. 更多信息

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values. 更多信息

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval. 更多信息

impl PartialEq for Side

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

测试 self 与 other 值是否相等，供 == 运算符使用。

fn ne(&self, other: &Rhs) -> bool

测试 != 运算符。默认实现几乎总是够用，除非有非常充分的理由，否则不应被覆盖。

若存在，此方法返回 self 与 other 值之间的排序关系。 更多信息

fn lt(&self, other: &Rhs) -> bool

测试小于（针对 self 与 other），供 < 运算符使用。 更多信息

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator. 更多信息

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator. 更多信息

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator. 更多信息
