These are values that can appear inside an rvalue (or an index place). They are intentionally limited to prevent rvalues from being nested in one another.

Copy: The value must be available for use afterwards.

This implies that the type of the place must be Copy; this is true by construction during build, but also checked by the MIR type checker.

Move: The value (including old borrows of it) will not be used again.

Safe for values of all types (modulo future developments towards ?Move). Correct usage patterns are enforced by the borrow checker for safe code. Copy may be converted to Move to enable "last-use" optimizations.
