Enum BlobCacheError 

pub enum BlobCacheError {
    Closed,
    InvalidConfig(String),
    InvalidBlob(String),
    ContentMismatch(String),
    Corrupt(String),
    Reconciliation(String),
    Policy(String),
    Io {
        operation: String,
        source: Error,
    },
}

Reports configuration, lifecycle, storage, or policy failures from crate::BlobCache.

Variants

Closed

The operation requires an open cache, but crate::BlobCache::close already completed.

InvalidConfig(String)

Cache construction received an invalid directory, byte limit, or frequency counter count.

InvalidBlob(String)

A blob ID is empty, too large, or otherwise invalid.

ContentMismatch(String)

Existing content for a blob ID differs from the new immutable payload.

Corrupt(String)

A committed cache entry is malformed or fails integrity validation.

Reconciliation(String)

On-disk state and the in-memory eviction policy could not be reconciled.

Policy(String)

The admission or eviction policy failed.

Io

A filesystem operation failed.

Fields

operation: String

Describes the filesystem operation that failed.

source: Error

Preserves the underlying I/O error.

Trait Implementations

impl Debug for BlobCacheError

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

Formats the value using the given formatter.

impl Display for BlobCacheError

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

Formats the value using the given formatter.

impl Error for BlobCacheError

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.
