"Derivative Works" shall mean any work, whether in Source or Object
|

form, that is based on (or derived from) the Work and for which the

of this License, Derivative Works shall not include works that remain

this License, each Contributor hereby grants to You a perpetual,

where such license applies only to those patent claims licensable
|

by such Contributor that are necessarily infringed by their
|

Contribution(s) alone or by combination of their Contribution(s)
|

with the Work to which such Contribution(s) was submitted. If You

cross-claim or counterclaim in a lawsuit) alleging that the Work
|

or a Contribution incorporated within the Work constitutes direct

that You distribute, all copyright, patent, trademark, and

attribution notices from the Source form of the Work,
|

excluding those notices that do not pertain to any part of
|

the Derivative Works; and

(d) If the Work includes a "NOTICE" text file as part of its

within such NOTICE file, excluding those notices that do not

pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,

within a display generated by the Derivative Works, if and

wherever such third-party notices normally appear. The contents

of the NOTICE file are for informational purposes only and

the conditions stated in this License.

any Contribution intentionally submitted for inclusion in the Work
|

by You to the Licensor shall be under the terms and conditions of

this License, without any additional terms or conditions.

Notwithstanding the above, nothing herein shall supersede or modify

with Licensor regarding such Contributions.

6. Trademarks. This License does not grant permission to use the trade

origin of the Work and reproducing the content of the NOTICE file.
|

7. Disclaimer of Warranty. Unless required by applicable law or
|

agreed to in writing, Licensor provides the Work (and each

Contributor provides its Contributions) on an "AS IS" BASIS,

WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

implied, including, without limitation, any warranties or conditions

of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

8. Limitation of Liability. In no event and under no legal theory,

whether in tort (including negligence), contract, or otherwise,

unless required by applicable law (such as deliberate and grossly
|

negligent acts) or agreed to in writing, shall any Contributor be
|

liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|

result of this License or out of the use or inability to use the
|

Work (including but not limited to damages for loss of goodwill,
|

work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|

has been advised of the possibility of such damages.
|

|

9. Accepting Warranty or Additional Liability. While redistributing

the Work or Derivative Works thereof, You may choose to offer,

and charge a fee for, acceptance of support, warranty, indemnity,
|

or other liability obligations and/or rights consistent with this
|

License. However, in accepting such obligations, You may act only
|

on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|

of your accepting any such warranty or additional liability.

// Package errors provides simple error handling primitives.
|
||||
//
|
||||
// The traditional error handling idiom in Go is roughly akin to
|
||||
//
|
||||
// if err != nil {
|
||||
// return err
|
||||
// }
|
||||
//
|
||||
// which applied recursively up the call stack results in error reports
|
||||
// without context or debugging information. The errors package allows
|
||||
// programmers to add context to the failure path in their code in a way
|
||||
// that does not destroy the original value of the error.
|
||||
//
|
||||
// Adding context to an error
|
||||
//
|
||||
// The errors.Wrap function returns a new error that adds context to the
|
||||
// original error by recording a stack trace at the point Wrap is called,
|
||||
// and the supplied message. For example
|
||||
//
|
||||
// _, err := ioutil.ReadAll(r)
|
||||
// if err != nil {
|
||||
// return errors.Wrap(err, "read failed")
|
||||
// }
|
||||
//
|
||||
// If additional control is required the errors.WithStack and errors.WithMessage
|
||||
// functions destructure errors.Wrap into its component operations of annotating
|
||||
// an error with a stack trace and an a message, respectively.
|
||||
//
|
||||
// Retrieving the cause of an error
|
||||
//
|
||||
// Using errors.Wrap constructs a stack of errors, adding context to the
|
||||
// preceding error. Depending on the nature of the error it may be necessary
|
||||
// to reverse the operation of errors.Wrap to retrieve the original error
|
||||
// for inspection. Any error value which implements this interface
|
||||
//
|
||||
// type causer interface {
|
||||
// Cause() error
|
||||
// }
|
||||
//
|
||||
// can be inspected by errors.Cause. errors.Cause will recursively retrieve
|
||||
// the topmost error which does not implement causer, which is assumed to be
|
||||
// the original cause. For example:
|
||||
//
|
||||
// switch err := errors.Cause(err).(type) {
|
||||
// case *MyError:
|
||||
// // handle specifically
|
||||
// default:
|
||||
// // unknown error
|
||||
// }
|
||||
//
|
||||
// causer interface is not exported by this package, but is considered a part
|
||||
// of stable public API.
|
||||
//
|
||||
// Formatted printing of errors
|
||||
//
|
||||
// All error values returned from this package implement fmt.Formatter and can
|
||||
// be formatted by the fmt package. The following verbs are supported
|
||||
//
|
||||
// %s print the error. If the error has a Cause it will be
|
||||
// printed recursively
|
||||
// %v see %s
|
||||
// %+v extended format. Each Frame of the error's StackTrace will
|
||||
// be printed in detail.
|
||||
//
|
||||
// Retrieving the stack trace of an error or wrapper
|
||||
//
|
||||
// New, Errorf, Wrap, and Wrapf record a stack trace at the point they are
|
||||
// invoked. This information can be retrieved with the following interface.
|
||||
//
|
||||
// type stackTracer interface {
|
||||
// StackTrace() errors.StackTrace
|
||||
// }
|
||||
//
|
||||
// Where errors.StackTrace is defined as
|
||||
//
|
||||
// type StackTrace []Frame
|
||||
//
|
||||
// The Frame type represents a call site in the stack trace. Frame supports
|
||||
// the fmt.Formatter interface that can be used for printing information about
|
||||
// the stack trace of this error. For example:
|
||||
//
|
||||
// if err, ok := err.(stackTracer); ok {
|
||||
// for _, f := range err.StackTrace() {
|
||||
// fmt.Printf("%+s:%d", f)
|
||||
// }

// }
