Functions

func ErrorFromV2 

func ErrorFromV2(st *status.Status) error

ErrorFromV2 converts status.Status message structure to error. Inverse to ErrorToV2 operation.

If result is not nil, it implements StatusV2. This fact should be taken into account only when passing the result to the inverse function ErrorToV2, casts are not compatibility-safe.

Below is the mapping of return codes to status instance types (with a description of parsing details). Note: notice if the return type is a pointer.

Successes:

  • status.OK: nil (this also includes nil argument).

Common failures:

Object failures:

Container failures:

Session failures:

func ErrorToV2 

func ErrorToV2(err error) *status.Status

ErrorToV2 converts error to status.Status message structure. Inverse to ErrorFromV2 operation.

If argument is the StatusV2 instance, it is converted directly. Otherwise, successes are converted with status.OK code w/o details and message, failures - with status.Internal and error text message w/o details.

func WriteInternalServerErr 

func WriteInternalServerErr(x *ServerInternal, err error)

WriteInternalServerErr writes err message to ServerInternal instance.
