[edit] Requirements

The type T satisfies MoveConstructible if

Given

  • rv, an rvalue expression of type T,
  • u, an arbitrary identifier.

The following expressions must be valid and have their specified effects.

Expression Post-conditions
T u = rv; The value of u is equivalent to the value of rv before the initialization.

The new value of rv is unspecified.

The new value of rv is unspecified.
