Overview ¶
Package toolbox does not currently implement any functionality. The subfolders within this package provide the full functionality of the toolbox.
Any method in the toolbox which returns an error object will return a custom error type implementing the go.imperva.dev/toolbox/errors.ExtendedError interface. The specific errors returned by the method are noted in its documentation. Each integer code corresponding the the specific error is unique across the entire toolbox.
To determine the specific type of error that was returned, you can use 1 of 3 methods:
◽ Use the errors.Is() method with new(ErrType) as the second argument where ErrType is the actual type of error that is expected. ◽ Use the errors.As() method to determine if you can convert the error into the given object. The advantage of this method is that you can then also access each error's custom fields. ◽ Cast the error object to an ExtendedError object and then use the Code() method to compare the error code to the corresponding error code constant defined as the error type with 'Code' appended to it (eg: ErrDoRequestFailureCode, ErrResourceWaitFailureCode)
Logging for methods within the toolbox is performed using either the zerolog logger object supplied in the context parameter for the method (generated by calling the logger instance's WithContext() function) or the global zerlog logger unless otherwise noted in the method's documentation.
The following error codes are allocated for each package:
◽ collection: 1001-1250 ◽ crypto: 1251-1500 ◽ gin: 2751-3000 ◽ gin/api: 3001-3250 ◽ gin/context: 3251-3500 ◽ gin/middleware: 3501-3750 ◽ i18n: 1501-1750 ◽ k8s: 1751-2000 ◽ net: 2001-2250 ◽ net/http: 2251-2500 ◽ strings: 2501-2750
