Enum OdosError

pub enum OdosError {
    Http(Error),
    Api {
        status: StatusCode,
        message: String,
    },
    Json(Error),

    RateLimit(String),
    Internal(String),
}

Comprehensive error types for the Odos SDK

This enum provides detailed error types for different failure scenarios, allowing users to handle specific error conditions appropriately.

Error Categories

• Network Errors: HTTP, timeout, and connectivity issues
• API Errors: Responses from the Odos service indicating various failures
• Input Errors: Invalid parameters or missing required data
• System Errors: Rate limiting and internal failures

Retryable Errors

Some error types are marked as retryable (see OdosError::is_retryable):

• Timeout errors
• Certain HTTP errors (5xx status codes, connection issues)
• Rate limiting errors
• Some API errors (server errors, rate limits)

Examples

use odos_sdk::{OdosError, Result};
use reqwest::StatusCode;

// Create different error types
let api_error = OdosError::api_error(StatusCode::BAD_REQUEST, "Invalid input".to_string());
let timeout_error = OdosError::timeout_error("Request timed out");
let rate_limit_error = OdosError::rate_limit_error("Too many requests");

// Check if errors are retryable
assert!(!api_error.is_retryable());  // 4xx errors are not retryable
assert!(timeout_error.is_retryable()); // Timeouts are retryable
assert!(rate_limit_error.is_retryable()); // Rate limits are retryable

// Get error categories for metrics
assert_eq!(api_error.category(), "api");
assert_eq!(timeout_error.category(), "timeout");
assert_eq!(rate_limit_error.category(), "rate_limit");

Trait Implementations

impl Debug for OdosError

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

Formats the value using the given formatter.

impl Display for OdosError

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

Formats the value using the given formatter.

impl Error for OdosError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
