Struct IcmpRateLimiter 

pub struct IcmpRateLimiter { /* private fields */ }

Rate limiter for ICMP Packet Too Big messages.

Tracks the last time an ICMP PTB was sent to each source address and enforces a minimum interval between messages to prevent floods.

Implementations

impl IcmpRateLimiter

pub fn new() -> Self

Create a new rate limiter.

Default: max 10 ICMP/sec per source (100ms interval).

pub fn with_interval(min_interval: Duration) -> Self

Create a rate limiter with custom interval.

pub fn should_send(&mut self, src_addr: Ipv6Addr) -> bool

Check if we should send an ICMP PTB to this source address.

Returns true if enough time has passed since the last ICMP to this source, or if this is the first ICMP to this source.

If true is returned, the internal state is updated to record this send.
