method DynHandle.set

Sets the override of layer (checked by policy Name { allow set if … } for a caller, the type and its refinements). The program's own code (no caller) may always set.

Example:

dynamic Limits {
  rps: u32 where 1..=1000 = 100
}

fn main() io {
  let l = Limits.get()
  l.rps.set(500)!
  print("{l.rps.get()}")
  print("{l.rps.check("5000") is DynError}")
}

500
true
