Canonical status codes for uProtocol operations.

These mirror the gRPC canonical codes, as required by the uProtocol specification; every transport and role reports failures through them. The application guide shows how callers act on the common ones.

Variants

Ok = 0

Not an error; the operation completed successfully.

Cancelled = 1

The operation was cancelled, typically by the caller.

Unknown = 2

Unknown error, or an error from a foreign error space.

InvalidArgument = 3

The caller specified an invalid argument, regardless of system state.

DeadlineExceeded = 4

A deadline expired before the operation could complete.

NotFound = 5

A requested entity (listener, topic, resource) was not found.

AlreadyExists = 6

The entity a caller attempted to create already exists.

PermissionDenied = 7

The caller lacks permission to execute the operation.

ResourceExhausted = 8

A resource (quota, buffer space, loan capacity) has been exhausted.

FailedPrecondition = 9

The system is not in a state required for the operation.

Aborted = 10

The operation was aborted, typically due to a concurrency conflict.

OutOfRange = 11

The operation was attempted past the valid range.

Unimplemented = 12

The operation is not implemented or supported by this transport or service.

Internal = 13

An internal invariant was broken; a bug in the implementation.

Unavailable = 14

The service or link is currently unavailable; retrying may succeed.

DataLoss = 15

Unrecoverable data loss or corruption.

Unauthenticated = 16

The request lacks valid authentication credentials.

Implementations

impl UCode

pub fn try_from_i32(value: i32) -> Result<Self, SerializationError>

Converts from the protobuf wire value.

Errors

Returns an error if value is not a defined code.

pub fn value(&self) -> i32

Returns the protobuf wire value of this code.

Trait Implementations

impl Clone for UCode

fn clone(&self) -> UCode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UCode

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

Formats the value using the given formatter.

impl PartialEq for UCode

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