Built-in IP detection providers

Each variant represents a specific provider service. Use with Config::builder() to select which providers to use.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

GoogleStun

Google STUN server (stun.l.google.com)

GoogleStun1

Google STUN server 1 (stun1.l.google.com)

GoogleStun2

Google STUN server 2 (stun2.l.google.com)

CloudflareStun

Cloudflare STUN server (stun.cloudflare.com)

GoogleDns

Google DNS via o-o.myaddr.l.google.com TXT

CloudflareDns

Cloudflare DNS via whoami.cloudflare TXT/CH

OpenDns

OpenDNS via myip.opendns.com

CloudflareHttp

Cloudflare 1.1.1.1/cdn-cgi/trace

Aws

AWS checkip.amazonaws.com

Implementations

impl BuiltinProvider

pub const ALL: &'static [BuiltinProvider]

All available built-in providers, ordered by expected performance.

Providers with both IPv4 and IPv6 support are listed first, followed by IPv4-only providers. Within each tier, UDP-based protocols (STUN, DNS) are preferred over HTTP due to lower overhead (no TLS handshake).

This order is used by Strategy::First. Run the benchmark example to find the optimal order for your network: cargo run --example benchmark --all-features

pub fn protocol(&self) -> Protocol

Get the protocol this provider uses

Trait Implementations

impl Clone for BuiltinProvider

fn clone(&self) -> BuiltinProvider

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuiltinProvider

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

Formats the value using the given formatter.

impl Display for BuiltinProvider

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

Formats the value using the given formatter.

impl Hash for BuiltinProvider

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 BuiltinProvider

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