Enum ResolveHosts

pub enum ResolveHosts {
    Always,
    Never,
    Auto,
}

Whether the system hosts file should be respected by the resolver.

Variants

Always

Always attempt to look up IP addresses from the system hosts file. If the hostname cannot be found, query the DNS.

Never

The DNS will always be queried.

Auto

Use local resolver configurations only when this resolver is not used in a DNS forwarder. This is the default.

Trait Implementations

impl Clone for ResolveHosts

fn clone(&self) -> ResolveHosts

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

Performs copy-assignment from source.

impl Debug for ResolveHosts

Formats the value using the given formatter.

impl Default for ResolveHosts

fn default() -> ResolveHosts

Returns the “default value” for a type.

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