Enum trust_dns_resolver::config::Protocol

#[non_exhaustive]
pub enum Protocol {
    Udp,
    Tcp,
}

The protocol on which a NameServer should be communicated with

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.

Udp

UDP is the traditional DNS port, this is generally the correct choice

Tcp

TCP can be used for large queries, but not all NameServers support it

Implementations

impl Protocol

pub fn is_datagram(self) -> bool

Returns true if this is a datagram oriented protocol, e.g. UDP

pub fn is_stream(self) -> bool

Returns true if this is a stream oriented protocol, e.g. TCP

pub fn is_encrypted(self) -> bool

Is this an encrypted protocol, i.e. TLS or HTTPS

Trait Implementations

impl Clone for Protocol

fn clone(&self) -> Protocol

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Protocol

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

Formats the value using the given formatter.

impl Default for Protocol

fn default() -> Self

Default protocol should be UDP, which is supported by all DNS servers

impl Display for Protocol

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

Formats the value using the given formatter.

impl PartialEq<Protocol> for Protocol

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