Function map_provider_error

Source 
pub fn map_provider_error(error: &ProviderError) -> (i32, &'static str)
Expand description

Maps provider errors to appropriate JSON-RPC error codes and messages.

This function translates internal provider errors into standardized JSON-RPC error codes and user-friendly messages that can be returned to clients. It follows JSON-RPC 2.0 specification for standard errors and uses OpenZeppelin-specific codes for extended functionality.

§Arguments

  • error - A reference to the provider error to be mapped

§Returns

Returns a tuple containing:

  • i32 - The error code (following JSON-RPC 2.0 and OpenZeppelin conventions)
  • &'static str - A static string describing the error type

§Error Code Mappings

  • InvalidAddress → -32602 (“Invalid params”)
  • NetworkConfiguration → -33004 (“Network configuration error”)
  • Timeout → -33000 (“Request timeout”)
  • RateLimited → -33001 (“Rate limited”)
  • BadGateway → -33002 (“Bad gateway”)
  • RequestError → -33003 (“Request error”)
  • Other and unknown errors → -32603 (“Internal error”)
