forcetypeassert

forcetypeassert finds type assertions which did forcely such as below.

func f() {
	var a interface{}
	_ = a.(int) // type assertion must be checked
}

You need to check if the assertion failed like so:

func f() {
	var a interface{}
	_, ok := a.(int)
	if !ok { // type assertion failed
  		// handle error
	}
}

Types

type Panicable

type Panicable struct {
	// contains filtered or unexported fields
}

Panicable stores panicable type assertions.

func (*Panicable) At

func (p *Panicable) At(i int) ast.Node

At returns the i-th panicable node.

func (*Panicable) Check

func (p *Panicable) Check(n ast.Node) bool

Check checks whether the node may occur panic or not.

func (*Panicable) Len

func (p *Panicable) Len() int

Len is number of panicable nodes.
