Types ¶
type Void ¶
type Void[V any] struct { // contains filtered or unexported fields }
Void is a generic wrapper type that can represent a value that may be explicitly undefined or unset, which is particularly useful for:
- JSON marshaling/unmarshaling where fields can be omitted
- Database operations where NULL values need to be distinguished from zero values
Supported types for V include:
- Basic types
- time.Time for timestamp handling
- []byte for binary data
- nil for explicit NULL values in databases
The zero value of Void[V] is considered undefined (valid = false).
