Enum tun2proxy::ArgDns

#[repr(C)]
pub enum ArgDns {
    Virtual = 0,
    OverTcp = 1,
    Direct = 2,
}

DNS query handling strategy

• Virtual: Use a virtual DNS server to handle DNS queries, also known as Fake-IP mode
• OverTcp: Use TCP to send DNS queries to the DNS server
• Direct: Do not handle DNS by relying on DNS server bypassing

Variants

Virtual = 0

OverTcp = 1

Direct = 2

Trait Implementations

impl Clone for ArgDns

fn clone(&self) -> ArgDns

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArgDns

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

Formats the value using the given formatter.

impl Default for ArgDns

fn default() -> ArgDns

Returns the “default value” for a type.

impl Ord for ArgDns

fn cmp(&self, other: &ArgDns) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ArgDns

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

impl PartialOrd for ArgDns

fn partial_cmp(&self, other: &ArgDns) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl ValueEnum for ArgDns

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.
