Struct DnsResolveMode 

pub struct DnsResolveMode(/* private fields */);

A vanity Extensions type for others to easily check if eager DNS resolution is enabled.

Implementations

impl DnsResolveMode

pub const fn eager() -> Self

Creates a new “eager” resolve mod

pub const fn lazy() -> Self

Creates a new “lazy” resolve mode

pub fn is_eager(&self) -> bool

Returns true if the DnsResolveMode is “eager”.

pub fn is_lazy(&self) -> bool

Returns true if the DnsResolveMode is “lazy”.

Trait Implementations

impl DnsExtension for DnsResolveMode

impl Eq for DnsResolveMode

impl Extension for DnsResolveMode

impl HttpExtension for DnsResolveMode

impl Ord for DnsResolveMode

fn cmp(&self, other: &DnsResolveMode) -> 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,

Restrict a value to a certain interval.

impl PartialEq for DnsResolveMode

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

impl PartialOrd for DnsResolveMode

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

Performs the conversion.

impl TryFrom<&str> for DnsResolveMode

type Error = Box<dyn Error + Sync + Send>
