nullany

Nullany is a library to have nullable types for Golang.

NullAny Struct

NullAny struct is for any type.

NullAny[T any]{}

It sets null to any type.

NewNullAny[T any](v T){}

It sets non-null to any type.

SetVal

It sets value to any type.

IsNil

It returns true if it is null, false otherwise.

Do(func)

It calls func when the val is non null.

DoThenElse(f1, f2)

It calls f1 when the value is null and calls f2 when the value is non-null

NullBool Struct

NullBool is a nullable bool type with handling logical AND and OR NOTICE: in NullBool's AND and OR, if one of bool value is null, then the result of AND and OR will be the other bool value. For example,

Null AND Null = Null

True AND Null = True
False AND Null = False

True OR Null = True
False OR Null = False

Please be sure the above behavior is what you expect before you use this library. If the behavior does not fit your need, please use the NullAny.
