smrcptr

相同的接收器指針（SMRCPTR）

不要混合接收器類型。為所有可用方法選擇指針或結構類型。

GO有關於它如何自動選擇值或方法接收器的規則，這很複雜並且可能導致錯誤。因此，這是一種常見的樣式建議^{1 2} 。

go install github.com/nikolaydubina/smrcptr@latest

 type Pancake struct {}

func NewPancake () Pancake { return Pancake {} }

func ( s * Pancake ) Fry () {}

func ( s Pancake ) Bake () {}

$ smrcptr ./...
/pancake.go:12:1: Pancake.Fry uses pointer
/pancake.go:10:1: Pancake.NewPancake uses value
/pancake.go:14:1: Pancake.Bake uses value

現有的襯裡

靜態

截至2022-11-30 ，它沒有檢測到指針和價值方法接收器的混合。大多數相關的分析儀ST1016僅檢查方法接收器的名稱。

$ staticcheck -checks ST1016 ./...    
main.go:9:18: methods on the same type should have the same receiver name (seen 1x " v " , 2x " s " ) (ST1016)

使用所有分析儀也無法檢測到它。

staticcheck -checks all ./...
main.go:9:18: methods on the same type should have the same receiver name (seen 1x " v " , 2x " s " ) (ST1016)
