Enum NatType 

pub enum NatType {
    None,
    FullCone,
    AddressRestricted,
    PortRestricted,
    Symmetric,
    Unknown,
}

Detected NAT type for the node

NAT type affects connectivity - some types are easier to traverse than others. The node automatically detects its NAT type and adjusts traversal strategies.

Variants

None

No NAT detected - direct public connectivity

The node has a public IP address and can accept connections directly.

FullCone

Full cone NAT - easiest to traverse

Any external host can send packets to the internal IP:port once the internal host has sent a packet to any external host.

AddressRestricted

Address-restricted cone NAT

External hosts can send packets only if the internal host has previously sent to that specific external IP.

PortRestricted

Port-restricted cone NAT

External hosts can send packets only if the internal host has previously sent to that specific external IP:port.

Symmetric

Symmetric NAT - hardest to traverse

Each outgoing connection gets a different external port. Requires prediction algorithms or relay fallback.

Unknown

NAT type not yet determined

The node hasn’t completed NAT detection yet.

Trait Implementations

impl Clone for NatType

fn clone(&self) -> NatType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NatType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NatType

fn default() -> NatType

Returns the “default value” for a type.

impl Display for NatType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for NatType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NatType

fn eq(&self, other: &NatType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
