Golang linter for check receiver type in method
Motivtation
From Go Wiki: Go Code Review Comments - The Go Programming Language
Don’t mix receiver types. Choose either pointers or struct types for all available method
Following code from Dave Chenney causes data race. Could you find it? This linter does it for you.
package main
import (
"fmt"
"time"
)
type RPC struct {
result int
done chan struct{}
}
func (rpc *RPC) compute() {
time.Sleep(time.Second) // strenuous computation intensifies
rpc.result = 42
close(rpc.done)
}
func (RPC) version() int {
return 1 // never going to need to change this
}
func main() {
rpc := &RPC{done: make(chan struct{})}
go rpc.compute() // kick off computation in the background
version := rpc.version() // grab some other information while we're waiting
<-rpc.done // wait for computation to finish
result := rpc.result
fmt.Printf("RPC computation complete, result: %d, version: %d\n", result, version)
}
