🔧 Core Modules

Error Handling (`must.go`)

// Assert operation success, panic on failure
value := utils.Must(getValue())

// Verify no error
utils.MustSuccess(doSomething())

// Verify boolean status
result := utils.MustOk(checkCondition())

Database Operations (`orm.go`)

type User struct {
    Name string `json:"name"`
    Age  int    `json:"age" default:"18"`
}

// Scan database data to struct
err := utils.Scan(dbData, &user)

// Convert struct to database value
value, err := utils.Value(user)

Data Validation (`validate.go`)

type Config struct {
    Email string `validate:"required,email"`
    Port  int    `validate:"min=1,max=65535"`
}

// Quick validation
err := utils.Validate(&config)

📦 Feature Modules

🍭 Data Processing Modules

Module	Function	Core API
candy	Type conversion syntactic sugar	`ToInt()`, `ToString()`, `ToBool()`
json	Enhanced JSON processing	`Marshal()`, `Unmarshal()`, `Pretty()`

🎯 Usage Examples

Complete Application Example

package main

import (
    "github.com/lazygophers/utils"
    "github.com/lazygophers/utils/config"
    "github.com/lazygophers/utils/candy"
    "github.com/lazygophers/utils/xtime"
)

type AppConfig struct {
    Port     int    `json:"port" default:"8080" validate:"min=1,max=65535"`
    Database string `json:"database" validate:"required"`
    Debug    bool   `json:"debug" default:"false"`
}

func main() {
    // 1. Load configuration
    var cfg AppConfig
    utils.MustSuccess(config.Load(&cfg, "config.json"))
    
    // 2. Validate configuration
    utils.MustSuccess(utils.Validate(&cfg))
    
    // 3. Type conversion
    portStr := candy.ToString(cfg.Port)
    
    // 4. Time processing
    cal := xtime.NowCalendar()
    log.Printf("Application started: %s", cal.String())
    
    // 5. Start server
    startServer(cfg)
}

Error Handling Best Practices

// ✅ Recommended: Use Must series functions
func processData() string {
    data := utils.Must(loadData())        // Panic on load failure
    utils.MustSuccess(validateData(data)) // Panic on validation failure
    return utils.MustOk(transformData(data)) // Panic on transform failure
}

// ✅ Recommended: Batch error handling
func batchProcess() error {
    return utils.MustSuccess(
        doStep1(),
        doStep2(),
        doStep3(),
    )
}

Database Operation Example

type User struct {
    ID    int64  `json:"id"`
    Name  string `json:"name" validate:"required"`
    Email string `json:"email" validate:"required,email"`
    Age   int    `json:"age" default:"0" validate:"min=0,max=150"`
}

func SaveUser(db *sql.DB, user *User) error {
    // Validate data
    if err := utils.Validate(user); err != nil {
        return err
    }
    
    // Convert to database value
    data, err := utils.Value(user)
    if err != nil {
        return err
    }
    
    // Save to database
    _, err = db.Exec("INSERT INTO users (data) VALUES (?)", data)
    return err
}

func GetUser(db *sql.DB, id int64) (*User, error) {
    var data []byte
    err := db.QueryRow("SELECT data FROM users WHERE id = ?", id).Scan(&data)
    if err != nil {
        return nil, err
    }
    
    var user User
    err = utils.Scan(data, &user)
    return &user, err
}
