Things that may go wrong using the Databoard.

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.

AlreadyExists

Entry with key already exists.

Fields

key: Arc<str>

Key of the entry to create.

AlreadyRemapped

Key is already remapped.

Fields

key: Arc<str>

Key to be remapped.

remapped: Arc<str>

The already existing remapping.

Assignment

Remapping of key is a value assignment.

Fields

key: Arc<str>

Key to be remapped.

value: Arc<str>

Value to be asssigned.

CreateRemapping

Value of target cannot be converted into a RemappingTarget.

Fields

source: Arc<str>

str to convert into target.

IsLocked

Entry with key is locked.

Fields

key: Arc<str>

Key of the wanted entry.

NoParent

Defined a remapping without giving a parent.

Fields

key: Arc<str>

Original key.

remapped: Arc<str>

Defined remapping.

NoTarget

Defined a remapping without valid target.

Fields

key: Arc<str>

Original key.

NotFound

Entry with key not stored.

Fields

key: Arc<str>

Key of the wanted entry.

WrongType

Entry with key is stored with a different type.

Fields

key: Arc<str>

Key of the wanted entry.

Unreachable(Arc<str>, u32)

Something impossible happened.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

Currently the default implementation is sufficient.

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.
