Trait Implementations

impl Clone for LookupIpStrategy

fn clone(&self) -> LookupIpStrategy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LookupIpStrategy

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

Formats the value using the given formatter.

impl Default for LookupIpStrategy

fn default() -> Self

Returns LookupIpStrategy::Ipv4thenIpv6 as the default.

impl PartialEq for LookupIpStrategy

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

This method tests for self and other values to be equal, and is used by ==.

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

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