Struct CacheLoadError 

pub struct CacheLoadError(pub String);

Error returned to waiter threads when a singleflight cache load fails.

The original typed error cannot be transferred across threads (the loader’s error type E is not available to waiters), so the error message is preserved as a String.

Trait Implementations

impl Clone for CacheLoadError

fn clone(&self) -> CacheLoadError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheLoadError

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

Formats the value using the given formatter.

impl Display for CacheLoadError

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

Formats the value using the given formatter.

impl Error for CacheLoadError

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<CacheLoadError> for String

fn from(e: CacheLoadError) -> Self

Converts to this type from the input type.
