Warning C26478

Don't use std::move on constant variables. (es.56)


This warning is to indicate that the use of std::move not consistent with how std::move is intended to be used.

Because const objects can't be moved, calling std::move on them has no effect. This pattern can result in unintended copies.

Code analysis name: NO_MOVE_OP_ON_CONST


struct node
    node* next;
    int id;

void foo(const node& n)
    const node local = std::move(n); // C26478 reported here
    // ...

To fix the issue, remove the redundant std::move.
