package go/ast
A DeferStmt node represents a defer statement.
Golang go/ast.DeferStmt type, End() and Pos() functions examples
Example 1:
func NodeDescription(n ast.Node) string {
switch n := n.(type) {
case *ast.ArrayType:
return "array type"
case *ast.AssignStmt:
return "assignment"
case *ast.DeferStmt:
return "defer statement"
...
}
Example 2:
func checkCurrentPosition(node ast.Node) string {
n := node.(*ast.DeferStmt)
endpos := n.End()
pospos := n.Pos()
if pospos != endpos {
return "not yet"
}
}
