Constructors

this this(T value)
this(const(T) value)
this(immutable(T) value): Constructs a SumType holding a specific value.
this this(const(T) value): Undocumented in source.
this this(immutable(T) value): Undocumented in source.
this this(SumType other)
this(const(SumType) other)
this(immutable(SumType) other): Constructs a SumType that's a copy of another SumType
this this(): Undocumented in source.

Destructor

~this ~this(): Calls the destructor of the SumType's current value.

Postblit

this(this) this(this): @disabled if any member type is non-copyable.

Members

Aliases

Types alias Types = FlattenSumTypes!(TypeArgs): The types a SumType can hold.
