Enum NatResolver 

pub enum NatResolver {
    Any,
    Upnp,
    PublicIp,
    ExternalIp(IpAddr),
    ExternalAddr(String),
    NetIf,
    None,
}

All builtin resolvers.

Variants

Any

Resolve with any available resolver.

Upnp

Resolve external IP via UPnP.

PublicIp

Resolve external IP via a network request.

ExternalIp(IpAddr)

Use the given IpAddr

ExternalAddr(String)

Use the given domain name as the external address to expose to peers. This is behaving essentially the same as NatResolver::ExternalIp, but supports domain names. Domain names are resolved to IP addresses using the OS’s resolver. The first IP address found is used. This may be useful in docker bridge networks where containers are usually queried by DNS instead of direct IP addresses. Note: the domain shouldn’t include a port number. Only the IP address is resolved.

NetIf

Resolve external IP via the network interface.

None

Resolve nothing

Implementations

impl NatResolver

pub async fn external_addr(self) -> Option<IpAddr>

Attempts to produce an IP address (best effort).

pub fn as_external_ip(self, port: u16) -> Option<IpAddr>

Returns the fixed ip, if it is NatResolver::ExternalIp or NatResolver::ExternalAddr.

In the case of NatResolver::ExternalAddr, it will return the first IP address found for the domain.

Trait Implementations

impl Clone for NatResolver

fn clone(&self) -> NatResolver

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NatResolver

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

Formats the value using the given formatter.

impl Default for NatResolver

fn default() -> NatResolver

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for NatResolver

where Self: FromStr, <Self as FromStr>::Err: Display,

fn deserialize<__D>(deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NatResolver

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

Formats the value using the given formatter.

impl FromStr for NatResolver

type Err = ParseNatResolverError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for NatResolver

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 NatResolver

fn eq(&self, other: &NatResolver) -> 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.

impl Serialize for NatResolver

where Self: Display,

fn serialize<__S>(&self, serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for NatResolver

impl StructuralPartialEq for NatResolver

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
