Variant.maybe


Description:

public Variant.maybe (VariantType? child_type, Variant? child)

Depending on if child is null, either wraps child inside of a maybe container or creates a Nothing instance for the given type.

At least one of child_type and child must be non-null. If child_type is non-null then it must be a definite type. If they are both non-null then child_type must be the type of child.

If child is a floating reference (see g_variant_ref_sink), the new instance takes ownership of child.

Parameters:

child_type

the VariantType of the child, or null

child

the child value, or null

Returns:

a floating reference to a new Variant maybe instance
