    MissingParameter(&'static str),
    WrongParameterRole,
    EmptyVersionList,
}

Variants

NoCommonVersion

Client and server share no supported protocol version.

MissingParameter(&'static str)

Tuple Fields

0: &'static str

Trait Implementations

impl Debug for SetupError

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

Formats the value using the given formatter.

impl Display for SetupError

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

Formats the value using the given formatter.

impl Error for SetupError

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 From<SetupError> for EndpointError

fn from(source: SetupError) -> Self

Converts to this type from the input type.

impl PartialEq for SetupError

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