pub enum ExactCacheError {
    Identity(DataCatalogError),
    InvalidEntryId,
    InvalidCommit(&'static str),
    Io {
        operation: &'static str,
        source: Error,
    },
    LockTimeout,
    UnsupportedPlatform,
}

Io

A native filesystem operation failed.

Trait Implementations

impl Debug for ExactCacheError

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

Formats the value using the given formatter.

impl Display for ExactCacheError

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

Formats the value using the given formatter.

impl Error for ExactCacheError

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<DataCatalogError> for ExactCacheError

fn from(source: DataCatalogError) -> Self

Converts to this type from the input type.
