Enum Failure 

pub enum Failure {
    Unreachable(String),
    TimedOut(i64),
    BadResponse(String),
}

Why no reply came back.

Three cases, because three are distinguishable by an implementation. A fourth that said “something went wrong” would be a Str with extra steps.

Variants

Unreachable(String)

Connect or write failed, or nothing is listening.

TimedOut(i64)

The exchange did not finish inside the deadline the implementation was given.

BadResponse(String)

Bytes arrived and were not an HTTP response.

Trait Implementations

impl Clone for Failure

fn clone(&self) -> Failure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Failure

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

Formats the value using the given formatter.

impl PartialEq for Failure

fn eq(&self, other: &Failure) -> 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 Eq for Failure
