Types 

type Header struct {
	Alg string `json:"alg"` // 16字节 (8+8) - string字段
	Typ string `json:"typ"` // 16字节 (8+8) - string字段
}

Header 结构体 - 32字节 (2个string，8字节对齐，无填充) 排列优化：string字段连续排列

func (Header) MarshalEasyJSON added in v1.1.0 

func (v Header) MarshalEasyJSON(w *jwriter.Writer)

MarshalEasyJSON supports easyjson.Marshaler interface

func (Header) MarshalJSON added in v1.1.0 

func (v Header) MarshalJSON() ([]byte, error)

MarshalJSON supports json.Marshaler interface

func (*Header) UnmarshalEasyJSON added in v1.1.0 

func (v *Header) UnmarshalEasyJSON(l *jlexer.Lexer)

type JwtConfig 

type JwtConfig struct {
	TokenKey string // 16字节 (8+8)
	TokenAlg string // 16字节 (8+8)
	TokenTyp string // 16字节 (8+8)
	TokenExp int64  // 8字节
}

JwtConfig 结构体 - 56字节 (4个字段，8字节对齐，无填充) 排列优化：int64放在最后，利用string的16字节对齐

type Payload 

type Payload struct {
	// 16字节字段组 (6个string字段，96字节)
	Sub string `json:"sub"` // 用户主体 - 16字节 (8+8)
	Aud string `json:"aud"` // 接收token主体 - 16字节 (8+8)
	Iss string `json:"iss"` // 签发token主体 - 16字节 (8+8)
	Dev string `json:"dev"` // 设备类型,web/app - 16字节 (8+8)
	Jti string `json:"jti"` // 唯一身份标识,主要用来作为一次性token,从而回避重放攻击 - 16字节 (8+8)
	Ext string `json:"ext"` // 扩展信息 - 16字节 (8+8)

	// 8字节字段组 (2个int64字段，16字节)
	Iat int64 `json:"iat"` // 授权token时间 - 8字节
	Exp int64 `json:"exp"` // 授权token过期时间 - 8字节
}

Payload 结构体 - 112字节 (8个字段，8字节对齐，无填充) 排列优化：string字段组在前(96字节)，int64字段组在后(16字节)

func (Payload) MarshalEasyJSON added in v1.1.0 

func (v Payload) MarshalEasyJSON(w *jwriter.Writer)

type SimplePayload added in v1.1.0 

type SimplePayload struct {
	Sub string // 用户主体 - 16字节 (8+8)
	Exp int64  // 授权token过期时间 - 8字节
}

SimplePayload 结构体 - 24字节 (string+int64，8字节对齐，无填充) 排列优化：int64放在string后面，利用8字节对齐

type Subject 

type Subject struct {
	// 8字节指针字段组 (2个字段)
	Header  *Header  // 8字节 - 指针字段
	Payload *Payload // 8字节 - 指针字段
	// contains filtered or unexported fields
}

Subject 结构体 - 32字节 (3个字段，8字节对齐，8字节填充) 排列优化：按字段类型分组，指针字段在前，接口字段在后
