Errors that can occur while managing dice, trays, expressions, or storage.

Variants

TrayNotFound(String)

The requested tray does not exist.

TrayAlreadyExists(String)

A tray with the requested name already exists.

DieNotFound(String)

The requested die does not exist.

DieAlreadyExists(String)

A die with the requested canonical name already exists.

SlotNotFound

The requested tray slot does not exist.

Fields

tray: String

Tray that was searched.

slot_id: u32

Slot identifier that was requested.

CannotModifyBuiltin(String)

Built-in dice cannot be modified or deleted.

CannotDeleteInUse

The die cannot be deleted because one or more trays reference it.

Fields

die: String

Canonical die name that was requested for deletion.

trays: Vec<String>

Trays that still reference the die.

StorageError(String)

Storage serialization or persistence failed.

InvalidExpression(String)

A dice expression is malformed or unsupported.

InvalidArguments(String)

A command or parser received invalid arguments.

InsufficientMatchingDice

A tray did not contain enough matching dice to satisfy a request.

Fields

tray: String

Tray that was searched.

die: String

Die name that was requested.

requested: usize

Number of matching dice requested.

available: usize

Number of matching dice available in the tray.

InvalidFaceCount

A custom die or counted expression had no faces.

InvalidNumericDie(String)

Numeric dice must have at least two faces.

InvalidName

A name was empty or contained whitespace.

Trait Implementations

impl Debug for DiceError

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

Formats the value using the given formatter.

impl Display for DiceError

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

Formats the value using the given formatter.

impl Error for DiceError

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.
