std.typecons

This module implements a variety of type constructors, i.e., templates that allow construction of new, useful general-purpose types.

Constructors

A destructor is present on this object, but not explicitly documented in the source.

isTuple eponymoustemplate isTuple(T): Returns true if and only if T is an instance of std.typecons.Tuple.

get T get(): Returns the value currently stored in the Rebindable.
opAssign void opAssign(T value): Overwrites the currently stored value with value.
reverse auto reverse(T t): Creates a copy of a Tuple with its fields in reverse order.

Rebindable struct Rebindable(T): Rebindable!(T) is a simple, efficient wrapper that behaves just like an object of type T, except that you can reassign it to refer to another object. For completeness, Rebindable!(T) aliases itself away to T if T is a non-const object type.
Unique struct Unique(T): Encapsulates unique ownership of a resource.

Rebindable template Rebindable(T): Rebindable!(T) is a simple, efficient wrapper that behaves just like an object of type T, except that you can reassign it to refer to another object. For completeness, Rebindable!(T) aliases itself away to T if T is a non-const object type.
Tuple template Tuple(Specs...): Tuple of values, for example Tuple!(int, string) is a record that stores an int and a string. Tuple can be used to bundle values together, notably when returning multiple values from a function. If obj is a Tuple, the individual members are accessible with the syntax obj[0] for the first field, obj[1] for the second, and so on.
tuple template tuple(Names...): Constructs a Tuple object instantiated and initialized according to the given arguments.
