Enum RegistryError 

pub enum RegistryError {
    NotFound(String),
    BadSignature(String),
    DigestMismatch(String),
    AlreadyRegistered(String),
    PublisherNotAllowed(String),
    Storage(String),
    Codec(String),
}

Failure modes for registry operations.

Variants

NotFound(String)

No entry for the requested name@version.

BadSignature(String)

HMAC verification failed against the configured signing key.

DigestMismatch(String)

BLAKE3 of the PTX text does not match manifest.digest.

AlreadyRegistered(String)

A manifest with the same name@version already exists.

PublisherNotAllowed(String)

The manifest’s publisher field is not in the registry’s configured allowlist. Only returned by the DiskRegistry when it has been built with Some(publisher_allowlist); the allowlist-less default and InMemoryRegistry never emit this. The string carries the manifest name for parity with the other rejection variants — the publisher itself is deliberately NOT echoed back to avoid leaking the allowlist contents through negative-result probing.

Storage(String)

The underlying on-disk artifact store rejected a put/get/list. The inner String is the ArtifactError’s Display; we collapse to a single variant because the registry layer treats every storage failure as a transient backend error rather than re-deriving one HTTP status per inner cause. Only emitted by DiskRegistry.

Codec(String)

bincode encode/decode of the on-disk manifest blob failed. The disk format pairs a KernelManifest with its PTX text under a single bincode envelope; a decode failure here usually means the blob was written by an incompatible bincode version, not that the bytes were tampered with (the artifact store’s HMAC catches the latter). Only emitted by DiskRegistry.

Trait Implementations

impl Debug for RegistryError

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

Formats the value using the given formatter.

impl Display for RegistryError

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

Formats the value using the given formatter.

impl Error for RegistryError

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>)
