func NewInvalidArgument

func NewInvalidArgument(message string, arguments []string) Error

NewInvalidArgument is a convenient function to returns an invalid argument error with a list of arguments that are invalid.

func NewRequestJSONInvalidErr

type ErrorCode

type ErrorCode int

ErrorCode is an integer representation of an error condition occurred within the system.

const (
	// NotAuthenticated is for operations that requires authentication
	// but the request is not properly authenticated.
	NotAuthenticated ErrorCode = 101 + iota

	// PermissionDenied occurs when the requested resource or operation
	// exists, but the request is not allowed for some reason.
	PermissionDenied

	// AccessKeyNotAccepted occurs when the request contains access key
	// (API key), but the access key is not accepted.
	AccessKeyNotAccepted

	// AccessTokenNotAccepted occurs when the request contains access token
	// but the access token is not accepted.
	AccessTokenNotAccepted

	// InvalidCredentials occurs when the information supplied by a user
	// to get authenticated is incorrect.
	InvalidCredentials

	// InvalidSignature is returned by an operation that requires a signature
	// and the provided signature is not valid.
	InvalidSignature

	// BadRequest is an error when the server does not understand the request.
	//
	// The same error is used for requests that does not conform to HTTP
	// protocol.
	// The same error may be used for requests that are missing arguments.
	BadRequest

	// InvalidArgument is an error when the server understand the request,
	// but the supplied argument is not valid
	InvalidArgument

	// Duplicated is an error that occurs when a resource to be saved is
	// a duplicate of an existing resource
	Duplicated

	// ResourceNotFound is returned because the requested resource
	// is not found, and this is unlikely due to a failure.
	//
	// The same error is used for operations that require a critical resource
	// to be available, and that resource is specified in the request.
	ResourceNotFound

	// NotSupported occurs when the server understands the request,
	// but the feature is not available due to a known limitation.
	//
	// Use this when the feature is not likely to be implemented in the near
	// future.
	NotSupported

	// NotImplemented occurs when the server understands the request,
	// but the feature is not implemented yet.
	//
	// Use this when the feature is likely to be implemented in the near
	// future.
	NotImplemented

	// ConstraintViolated occurs when a resource cannot be saved because
	// doing so would violate a constraint.
	ConstraintViolated

	// IncompatibleSchema occurs if because the saving record is incompatible
	// with the existing schema.
	IncompatibleSchema

	// AtomicOperationFailure occurs when a batch operation failed because
	// it failed partially, and the batch operation is required to be atomic
	AtomicOperationFailure

	// PartialOperationFailure occurs when a batch operation failed because
	// it failed partially, and the batch operation is not required to be atomic
	PartialOperationFailure

	// UndefinedOperation is an operation that is not known to the system
	UndefinedOperation

	// PluginUnavailable occurs when the configured plugin is not available at
	// the moment
	PluginUnavailable

	// PluginTimeout occurs when an operation carried by a plugin is timed out
	PluginTimeout
)

A list of all expected errors.

Naming convention: * Try not to end an error name with "Error" * "NotAccepted" refers to information that seems valid but still not accepted for some reason * "Bad" refers to information that is malformed or in a corrupted format * "Invalid" refers to information that is not correct

const (

	// UnexpectedError is for an error that is not likely to happen or
	// an error that cannot be classified into any other error type.
	//
	// Refrain from using this error code.
	UnexpectedError ErrorCode = 10000 + iota
	UnexpectedUserInfoNotFound
	UnexpectedUnableToOpenDatabase
	UnexpectedPushNotificationNotConfigured
	InternalQueryInvalid
