结构体 Ipv4Addr 

pub struct Ipv4Addr(/* private fields */);

std::net::Ipv4Addr 的 no_std 实现。

注意：由于我们计划在该类型一旦稳定后用 core::net::Ipv4Addr 替换它，因此该类型本身的标识不应被视为 semver 稳定。不过，其对外提供的接口是稳定的，它们是 core::net::Ipv4Addr 所提供接口的一个子集。

trait 实现

impl AsRef<[u8; 4]> for Ipv4Addr

fn as_ref(&self) -> &[u8; 4]

将该类型转换为（通常按类型推导出的）输入类型的共享引用。

impl Clone for Ipv4Addr

fn clone(&self) -> Ipv4Addr

返回该值的一个副本。更多信息

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

Performs copy-assignment from source. 更多信息

impl Debug for Ipv4Addr

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

使用给定的格式化器格式化该值。更多信息

impl From<[u8; 4]> for Ipv4Addr

fn from(value: [u8; 4]) -> Self

将该输入类型转换为此类型。

impl From<Ipv4Addr> for Ipv4Addr

Available on crate feature std only.

fn from(addr: Ipv4Addr) -> Self

将该输入类型转换为此类型。

impl From<Ipv4Addr> for Ipv4Addr

Available on crate feature std only.

fn from(value: Ipv4Addr) -> Self

将该输入类型转换为此类型。

impl From<Ipv4Addr> for ServerName<'_>

fn from(v4: Ipv4Addr) -> Self

将该输入类型转换为此类型。

impl Hash for Ipv4Addr

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

将该值送入给定的 Hasher 中。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 PartialEq for Ipv4Addr

fn eq(&self, other: &Ipv4Addr) -> bool

测试 self 与 other 值是否相等，供 == 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 TryFrom<&str> for Ipv4Addr

type Error = AddrParseError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

执行转换。
