Error Types

The SDK provides specific error types for different failure scenarios:

gotype APIError struct {
    Code    int
    Message string
}

type ValidationError struct {
    Field   string
    Message string
}

type TransactionError struct {
    TxHash string
    Reason string
}

type RateLimitError struct {
    RetryAfter int // seconds
}

Error Handling Pattern

goimport "github.com/ayush78490/Go-Predix/gopredix-sdk/errors"

// Type assertion for specific errors
if err := client.CreateMarket(ctx, req); err != nil {
    switch e := err.(type) {
    case *errors.ValidationError:
        log.Printf("Validation failed: %s = %s\n", e.Field, e.Message)
    case *errors.APIError:
        if e.Code == 429 {
            log.Println("Rate limited, retry later")
        }
    case *errors.TransactionError:
        log.Printf("Transaction failed: %s\n", e.TxHash)
    default:
        log.Fatal(err)
    }
}
