Overview ¶

Package option provides a typed Some/None carrier for fields that may be present or absent. Pure value semantics — no pointer, no nil. Read Val only when Has is true.

Idiomatic uses include marshalling fields that bind to a ZeroToOne cardinality, configuration values that may be unset, and any API where the difference between "absent" and "zero value" matters.

Types ¶

type Option ¶

type Option[T any] struct {
	Val T
	Has bool
}

Option is the typed Some/None carrier.

func None ¶

func None[T any]() (opt Option[T])

None returns an absent Option[T] — Has is false and Val carries the zero value of T.

func Some ¶

func Some[T any](v T) (opt Option[T])

Some wraps a value in a present Option[T].
