Failures of the registration APIs. Never reaches the wire.

Variants

AlreadyRegistered

The name exists with a DIFFERENT configuration. field names the first field that differs, by type — never a string a consumer must parse.

Fields

name: String

The contested roster key.

field: ChannelConfigField

The first field of the compared set that did not match.

NotRegistered

Quiesce or probe named a channel that is not on the roster.

Fields

name: String

The absent roster key.

AlreadyQuiesced

Re-quiesce under a DIFFERENT reason. Quiesce is one-way and its reason is written once; a second reason would silently lose one of the two.

Fields

name: String

The already-quiesced roster key.

reason: String

The reason already on record — not the one that was just refused.

SchemaRejected

The schema bytes did not parse as JSON, or did not compile as a JSON Schema.

Fields

name: String

The channel whose schema was refused.

message: String

The parser’s or the compiler’s own diagnostic.

DurableInitFailed

Durable initialization over the shared store failed.

Fields

name: String

The channel whose durable construction failed.

message: String

The library’s own diagnostic.

CapNotConfigured

Runtime registration was attempted with no cap declared. Refused rather than admitted: unbounded-by-default is not a bound.

Fields

cap: &'static str

The config key the operator must declare.

CapReached

The declared cap is already reached.

Fields

cap: &'static str

The config key that declared the bound.

limit: usize

The configured value, so the refusal states the bound it enforced.

RosterUnavailable

The roster lock is poisoned.

Fields

message: String

The diagnostic for the unavailable roster.

Trait Implementations

impl Debug for ChannelRegistryError

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

Formats the value using the given formatter.

impl Display for ChannelRegistryError

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

Formats the value using the given formatter.

impl Error for ChannelRegistryError

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.
