Enum OpportunisticEncryption 

#[non_exhaustive]
pub enum OpportunisticEncryption {
    Disabled,
}

Configuration for enabling RFC 9539 opportunistic encryption.

Controls how a recursive resolver probes name servers to discover if they support encrypted transports.

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.

Disabled

Opportunistic encryption will not be performed.

Implementations

impl OpportunisticEncryption

pub fn is_enabled(&self) -> bool

Returns true if opportunistic encryption is enabled.

pub fn max_concurrent_probes(&self) -> Option<u8>

Returns the maximum number of concurrent probes if opportunistic encrypt is enabled.

Trait Implementations

impl Clone for OpportunisticEncryption

fn clone(&self) -> OpportunisticEncryption

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpportunisticEncryption

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

Formats the value using the given formatter.

impl Default for OpportunisticEncryption

fn default() -> OpportunisticEncryption

Returns the “default value” for a type.

impl PartialEq for OpportunisticEncryption

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