Enum LookupError 

#[non_exhaustive]
pub enum LookupError {
    ConfigStoreInvalid,
    KeyInvalid,
    KeyTooLong,
    ValueTooLong,
    TooManyLookups,
    Other,
}

Errors thrown when a config store lookup failed.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ConfigStoreInvalid

The config store handle used for a lookup was invalid.

KeyInvalid

The config store key provided was invalid.

KeyTooLong

The config store key provided was too long.

ValueTooLong

The config store value was too long for the provided buffer length.

TooManyLookups

Too many lookups have been performed

Other

A config store lookup failed for some other reason.

Trait Implementations

impl Debug for LookupError

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

Formats the value using the given formatter.

impl Display for LookupError

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

Formats the value using the given formatter.

impl Error for LookupError

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.
