Enum HappyEyeballsError 

#[non_exhaustive]
pub enum HappyEyeballsError<T> {
    Timeout(Duration),
    NoProgress,
    Error(T),
}

Error returned when the happy eyeballs algorithm finishes.

It contains the inner error if an underlying future errored (this will always be the first error)

Otherwsie, the enum indicates what went wrong.

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.

Timeout(Duration)

The timeout was reached.

NoProgress

No progress can be made.

Error(T)

An error occurred during the underlying future.

Trait Implementations

impl<T: Debug> Debug for HappyEyeballsError<T>

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

Formats the value using the given formatter.

impl<T> Display for HappyEyeballsError<T>

where T: Display,

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

Formats the value using the given formatter.

impl<T> Error for HappyEyeballsError<T>

where T: Error + 'static,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<T: PartialEq> PartialEq for HappyEyeballsError<T>

fn eq(&self, other: &HappyEyeballsError<T>) -> 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.
