Enum ValueCodecRegistryError 

pub enum ValueCodecRegistryError {
    DuplicateId {
        id: &'static str,
        sources: Vec<ValueCodecRegistrationSource>,
    },
}

Failure while freezing a value-codec registry.

Freezing rejects duplicate stable IDs and reports the lexically first conflicting ID together with all of its declaration sites. Sources are sorted by their fields; repeated identical sources are retained because each registration is reported.

The registry returns this error when ValueStringCodecRegistry::try_global or ValueBytesCodecRegistry::try_global encounters conflicting linked registrations.

Examples

use qubit_codec::ValueBytesCodecRegistry;
use qubit_codec::ValueCodecRegistryError;

fn describe_registry_error(error: ValueCodecRegistryError) -> String {
    match error {
        ValueCodecRegistryError::DuplicateId { id, sources } => {
            format!("duplicate value codec ID {id} from {} source(s)", sources.len())
        }
    }
}

if let Err(error) = ValueBytesCodecRegistry::try_global() {
    let description = describe_registry_error(error);
    assert!(description.starts_with("duplicate value codec ID "));
}

Variants

DuplicateId

Multiple registrations claim one stable ID.

Fields

id: &'static str

Conflicting stable ID.

sources: Vec<ValueCodecRegistrationSource>

Registration sources in deterministic order.

Trait Implementations

impl Clone for ValueCodecRegistryError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueCodecRegistryError

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

Formats the value using the given formatter.

impl Display for ValueCodecRegistryError

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

Formats the value using the given formatter.

impl Error for ValueCodecRegistryError

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>)
