Expand description

A compare rule to restrict an argument syscall

Implementations§

source§

impl Comparator

source

pub fn new(arg: u32, op: Cmp, datum_a: u64, datum_b: Option<u64>) -> Self

Set a constraint for a syscall argument.

  • The first argument is the syscall argument index, 0 would be the first argument.
  • The second argument selects a compare operation like equals-to, greather-than, etc.
  • The third argument is the value it’s going to be compared to.
  • The forth argument is only used when using Cmp::MaskedEq, where datum_a is used as a mask and datum_b is the value the result is compared to.
