In the interface the read method returns an interface{} whereas the CapacityResponse returns an int32. Go’s interface matching is done strictly on the signature of the function and does not take into consideration that an int32 does implement the interface{}. You can work around this by having two methods: // This does the work func … Read more
The quotes in your query param seem to be causing the error at the server. Try something like this apiURL := “http://localhost:8080/api/history/resources/count” req, err := http.NewRequest(“GET”, apiURL, nil) if err != nil { log.Fatal(err) } apiParams := req.URL.Query() apiParams.Add(“startedAfter”, “2021-03-06T15:27:13.894415787+0200”) req.URL.RawQuery = apiParams.Encode() res, err := http.DefaultClient.Do(req) try that and revert. solved Getting 400 after … Read more

Slices are references to arrays. When modifying a slice without copying it, the underlaying array will be modified. Therefore, all slices that point to the same underlaying array will see this change. solved Why does this goroutine behave like it’s call by reference?
Sometimes you need to incrementally build a new string, i.e. character per character. In order to do this efficiently many programming languages add the so-called string builders. This allows to essentially modify an array of characters rather than recreating a new string every time. Check the official example: package main import ( “fmt” “strings” ) … Read more
Are you using terminal with no GUI? If you do not have access to an IDE, all I can think about is using Linux command like grep to search in a lot of files inside of the package folder for var <variableName> terms. If you have a package named test with 100 files and you … Read more
As @Sergio Tulentsev pointed out, you are assigning ModifyDBClusterSnapshotAttributeInput type to the variable input, that is a CreateDBClusterSnapshotInput type. There would be a few solutions to handle this problem, but the easiest way would be to make a method for each type struct that returns a compatible type for input like this; func (createInput CreateDBClusterSnapshotInput) … Read more
It is because a slice is already a pointer (https://golang.org/ref/spec#Slice_types). So to set a pointer to a slice is setting a pointer to a pointer. So just remeber if you are dealing with slices they are pointers to arrays. More information how the slices are used as a pointer are here: https://golang.org/doc/effective_go.html#slices solved Weird behavior … Read more
There’s no built-in method what you’re looking for (merging slices). However, you can use append method like: s.setGrade(append([]int{80}, s.Grade[1:]…)) If you had to update two grade ints then you could have done: s.setGrade(append([]int{80,95}, s.Grade[2:]…)) 1 solved Index slice within Main func when using setGrade()
Introduction Index slice within Main func when using setGrade() is a common problem encountered when working with arrays in programming. It can be solved by using a combination of indexing and slicing techniques. Indexing is used to access individual elements of an array, while slicing is used to access a range of elements. By combining … Read more
Have you tried anything? There’s lots of ways to do what you’re trying to do. Some more peprformant than others, some easier to write… This would be a quick way to implement what you need: func PrintStr(m map[string]interface{}) { parts := make([]string, 0, len(m)) for k, v := range m { parts = append(parts, fmt.Sprintf(“%s=%v”, … Read more
You are jammed in runtime (see https://godoc.org/runtime) presumably because of poor choices in the com/smdduck/xsys/xcron/NewRateLimiter But no idea what to recommend, as there is no source code Voting to close as off-topic due to a lack of code to look at 2 solved How to analyze this Golang cpu pprof snapshot?

The channel can only take one variable so you are right that you need to define a structure to hold you results, however, you are not actually using this to pass into your channel. You have two options, either modify executeCmd to return a results: func executeCmd(command, port string, hostname string, config *ssh.ClientConfig) results { … Read more
