concept bool MoveConstructible =
The concept MoveConstructible is satisfied if T is a reference type, or if it is an object type where an object of that type can constructed from an rvalue of that type in both direct- and copy-initialization contexts, with the usual semantics.
More precisely, if T is an object type, then MoveConstructible<T> is satisfied only if given
-
rv, an rvalue of typeT, and -
u2, a distinct object of typeTequal torv,
the following are true:
- After the definition T u = rv;,
uis equal tou2; -
T{rv}is equal tou2; and - If
Tis not const-qualified, thenrv's resulting state (after the definition/expression is evaluated in either bullets above) is valid but unspecified; otherwise, it is unchanged.
