BreakerError

public struct BreakerError: Error

An Error representing a failure within the CircuitBreaker call.

BreakerError is intended to be extended to describe command context errors.

Usage Example:

extension BreakerError {
  public static let URLEncodingError = BreakerError(reason: "URL Could Not Be Found")
  public static let responseError = BreakerError(reason: "Invalid Response Error")
}

func myContextFunction(invocation: Invocation<(String), Void, String>) {
  guard let url = URL(string: "http://mysever.net/path/\(invocation.commandArgs)") else {
    invocation.notifyFailure(error: BreakerError.URLEncodingError)
  }

  URLSession.shared.dataTask(with: URLRequest(url: url)) { result, res, err in
    guard let result = result else {
      invocation.notifyFailure(error: BreakerError.responseError)
      return
    }

    invocation.notifySuccess()
  }.resume()
}
