枚举 AlertDescription 

#[non_exhaustive]
pub enum AlertDescription {
    CloseNotify,
    UnexpectedMessage,
    BadRecordMac,
    DecryptionFailed,
    RecordOverflow,
    DecompressionFailure,
    HandshakeFailure,
    NoCertificate,
    BadCertificate,
    UnsupportedCertificate,
    CertificateRevoked,
    CertificateExpired,
    CertificateUnknown,
    IllegalParameter,
    UnknownCA,
    AccessDenied,
    DecodeError,

    ProtocolVersion,
    InsufficientSecurity,
    InternalError,
    InappropriateFallback,
    UserCanceled,
    NoRenegotiation,
    MissingExtension,
    UnsupportedExtension,
    CertificateUnobtainable,
    UnrecognisedName,
    BadCertificateStatusResponse,

    UnknownPSKIdentity,

    NoApplicationProtocol,
    EncryptedClientHelloRequired,
    Unknown(u8),
}

此 AlertDescription TLS 协议枚举。 Values in this enum are taken 从 the various RFCs covering TLS, 并 are listed by IANA. 此 Unknown item is 用 when processing unrecognised ordinals.

变体 (Non-exhaustive)

非穷尽枚举未来可能添加新的变体。因此，在对非穷尽枚举的变体进行模式匹配时，必须额外增加一个通配符分支以涵盖未来的新变体。

impl AlertDescription

pub fn to_array(self) -> [u8; 1]

pub fn as_str(&self) -> Option<&'static str>

Trait 实现

impl Clone for AlertDescription

fn clone(&self) -> AlertDescription

返回值的副本。 更多信息

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

Performs copy-assignment 从 source. 更多信息

impl Debug for AlertDescription

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

使用给定的格式化器格式化此值。 更多信息

impl From<AlertDescription> for u8

fn from(value: AlertDescription) -> Self

从输入类型转换为此类型。

impl From<CertificateError> for AlertDescription

fn from(e: CertificateError) -> Self

从输入类型转换为此类型。

impl From<InvalidMessage> for AlertDescription

fn from(e: InvalidMessage) -> Self

从输入类型转换为此类型。

impl From<u8> for AlertDescription

fn from(x: u8) -> Self

impl PartialEq for AlertDescription

fn eq(&self, other: &AlertDescription) -> 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。
