Subject: rust(lint): replace checked_mul with saturating_mul
X-Git-Tag: suricata-7.0.0-beta1~1517
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d0772e04b1483c342b3f639ef11309f342f8145b;p=thirdparty%2Fsuricata.git

rust(lint): replace checked_mul with saturating_mul

When defaulting checked_mul to u64::max, Rust has a method
that does the same thing called saturating_mul.
