Variants

PromptCache(PromptCacheError)

Backend-neutral manifest geometry or identity is invalid.

Io

A filesystem operation failed.

Fields

action: &'static str

Filesystem action that failed.

path: PathBuf

Path involved in the failed action.

source: Error

Underlying filesystem failure.

ManifestJson(Error)

A manifest could not be encoded or decoded.

MalformedStorage(String)

Filesystem publication metadata is malformed.

UnsafeShardPath(String)

A shard path could escape the prompt-cache directory.

MissingShard(PathBuf)

A manifest referenced a missing shard.

MalformedShard

A safetensors shard had missing, extra, or corrupt arrays.

Fields

path: PathBuf

Invalid shard path.

reason: String

Structural or data validation failure.

InvalidPromptCachePath(PathBuf)

The target path cannot be published atomically.

PromptCacheExists(PathBuf)

The destination exists and explicit replacement was not requested.

Trait Implementations

impl Debug for PromptCachePersistenceError

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

Formats the value using the given formatter.

impl Display for PromptCachePersistenceError

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

Formats the value using the given formatter.

impl Error for PromptCachePersistenceError

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<PromptCacheError> for PromptCachePersistenceError

fn from(source: PromptCacheError) -> Self

Converts to this type from the input type.
