Enum PortState 

pub enum PortState {
    Empty,
    Full,
    NonEmpty,
    NonFull,
    Equals(u64),
    LessThan(u64),
    GreaterThan(u64),
    EqualsOrLessThan(u64),
    EqualsOrGreaterThan(u64),
}

A predicate on the state of a port, used in salvo conditions.

These predicates test the current packet count at a port against various conditions like empty, full, or numeric comparisons.

Variants

Empty

Port has zero packets.

Full

Port is at capacity (always false for infinite ports).

NonEmpty

Port has at least one packet.

NonFull

Port is below capacity (always true for infinite ports).

Equals(u64)

Port has exactly this many packets.

LessThan(u64)

Port has fewer than this many packets.

GreaterThan(u64)

Port has more than this many packets.

EqualsOrLessThan(u64)

Port has at most this many packets.

EqualsOrGreaterThan(u64)

Port has at least this many packets.
