The unified Katra error type.

Variants

InvalidArgument(&'static str)

Invalid argument; the &'static str names the argument.

NotSupported(String)

Operation not supported; the message names the capability.

OutOfBudget

A budget was exceeded.

Fields

resource: &'static str

Budget name, e.g. "staging_bytes".

requested: u64

Amount requested.

available: u64

Amount available.

Io(ErrorKind, String)

I/O failure.

Protocol(String)

Protocol violation (trace format, ABI framing).

NotFound(String)

Resource not found.

AlreadyExists(String)

Resource already exists.

Corrupt(String)

Corrupt data.

Timeout

Timeout.

Fields

what: &'static str

What timed out.

timeout_ns: u64

Timeout in nanoseconds.

Sync(String)

Synchronization invariant violation.

FallbackUnavailable(&'static str)

Fallback unavailable.

Internal(&'static str)

Internal invariant violation.

Implementations

impl KatraError

pub fn category(&self) -> ErrorCategory

The coarse category of this error.

Trait Implementations

impl Clone for KatraError

fn clone(&self) -> KatraError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KatraError

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

Formats the value using the given formatter.

impl Display for KatraError

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

Formats the value using the given formatter.

impl Eq for KatraError

impl Error for KatraError

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<Error> for KatraError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl PartialEq for KatraError

fn eq(&self, other: &KatraError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
