Go Type conversions Basic Type Conversion
Example
There are two basic styles of type conversion in Go:
// Simple type conversion
var x := Foo{} // x is of type Foo
var y := (Bar)Foo // y is of type Bar, unless Foo cannot be cast to Bar, then compile-time error occurs.
// Extended type conversion
var z,ok := x.(Bar) // z is of type Bar, ok is of type bool - if conversion succeeded, z has the same value as x and ok is true. If it failed, z has the zero value of type Bar, and ok is false.
