!=

fn pub !=(other: ref Self) -> Bool {
(self == other).false?
}
fn pub !=(other: ref Self) -> Bool
Returns true
if self
and the given object are not equal to each other.
==

fn pub ==(other: ref Error) -> Bool {
match (self, other) {
case (InvalidHost, InvalidHost) -> true
case (ServerError, ServerError) -> true
case (Other(a), Other(b)) -> a == b
case _ -> false
}
}
fn pub ==(other: ref Error) -> Bool
Returns true
if self
and the given object are equal to each other.
This operator is used to perform structural equality. This means two objects residing in different memory locations may be considered equal, provided their structure is equal. For example, two different arrays may be considered to have structural equality if they contain the exact same values.
fmt

fn pub fmt(formatter: mut Formatter) {
match self {
case InvalidHost -> formatter.tuple('InvalidHost').finish
case ServerError -> formatter.tuple('ServerError').finish
case Other(e) -> formatter.tuple('Other').field(e).finish
}
}
fn pub fmt(formatter: mut Formatter)
Formats self
in a human-readable format for debugging purposes.
to_string

fn pub to_string -> String {
match self {
case InvalidHost -> "the hostname can't be resolved"
case ServerError -> 'the DNS server returned an error'
case Other(e) -> e.to_string
}
}
fn pub to_string -> String
Converts self
to a String
.
