Macro far 

far!() { /* proc-macro */ }

Available on crate feature bank only.

Take a far pointer to a banked function, for heterogeneous dispatch.

far!(path::to::f) yields a Far to the banked function f (resolved through the module’s group). Call .erase() on it to drop the static group and collect functions from different banks into a single [DynFar<..>; N] table, then dispatch with runtime arguments.

Examples

let table: [DynFar<fn(u8)>; 2] = [
    far!(sound::play).erase(),
    far!(enemy::ai).erase(),
];
for entry in &table {
    entry.invoke(bank, (level,));   // switch to each one's bank, run, restore
}
