Discovery errors

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.

Implementations

impl DiscoveryError

pub fn from_err<T>(provenance: &'static str, source: T) -> DiscoveryError

where T: Error + Send + Sync + 'static,

Creates a new user error from an arbitrary error type.

pub fn from_err_box( provenance: &'static str, source: Box<dyn Error + Sync + Send>, ) -> DiscoveryError

Creates a new user error from an arbitrary boxed error type.

Trait Implementations

impl Debug for DiscoveryError

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

Formats the value using the given formatter.

impl Display for DiscoveryError

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

Formats the value using the given formatter.

impl Error for DiscoveryError

where DiscoveryError: Debug + Display,

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

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

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 ErrorCompat for DiscoveryError

fn backtrace(&self) -> Option<&Backtrace>

Returns a [Backtrace][] that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl From<PkarrError> for DiscoveryError

fn from(err: PkarrError) -> DiscoveryError

Converts to this type from the input type.
