Trying to marshal a struct with no public fields nor custom marshalingSCC-SA9005
The encoding/json and encoding/xml packages only operate on exported fields in structs, not unexported ones. It is usually an error to try to (un)marshal structs that only consist of unexported fields.
Return of `nil` value detectedCRT-D0013
If a return statement returns a value that evaluates to nil, it is better to return nil explicitly.
Off-by-one error detectedCRT-D0015
An off-by-one error happens due to incorrectly handled edge-cases.
Issues with `cancel` func returned by context.WithCancel detectedVET-V0011
The cancellation function returned by context.WithCancel, WithTimeout, and WithDeadline must be called or the new context will remain live until its parent context is cancelled. (The background context is never cancelled.) This is usually an issue either because the variable was assigned to the blank identifier, or because there exists a control-flow path from the call to a return statement and that path does not "use" the cancel function.
Incomplete condition detectedCRT-D0017
Some conditions become unsafe when not exhaustive. For example, in the following example, the array xs may be of zero length, but not necessarily nil (say, when xs := make([]someType, 0)). Hence, the second part of the condition will panic if there are no elements yet.
