Nil Safety

Route by Type

  • •Interface nil trap → see interface/
  • •Map nil writes → see map/
  • •Slice zero-value → see slice/
  • •Pointer receivers → see pointer/

Quick Check

  • • Check pointers before deref
  • • Check maps before write
  • • Typed nil != nil interface

Common Gotcha

go
var p *int
if p == nil {  // true
    fmt.Println("nil pointer")
}
