can i create in golang a map with any key type and any value type ? , something like :
dict1 := map[interface]interface{}
Thanks a lot !
From the language spec for the key type:
The comparison operators == and != must be fully defined for operands of the key type;
So most types can be used as a key type, however:
Slice, map, and function values are not comparable
and thus cannot be used as a map-key.
The value type can be any or (any or interface{}) type.
type mytype struct{}
type ss []string
_ = make(map[interface{}]interface{}) // this works...
_ = make(map[any]any) // ... semantically the same
_ = make(map[mytype]any) // even a struct
_ = make(map[ss]any) // FAILS: invalid map key type ss
