smrcptr

相同的接收器指针（SMRCPTR）

不要混合接收器类型。为所有可用方法选择指针或结构类型。

GO有关于它如何自动选择值或方法接收器的规则，这很复杂并且可能导致错误。因此，这是一种常见的样式建议^{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

现有的衬里

静态

截至2022-11-30 ，它没有检测到指针和价值方法接收器的混合。大多数相关的分析仪ST1016仅检查方法接收器的名称。

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

使用所有分析仪也无法检测到它。

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