Error returned when a Round action is illegal

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.

WrongPhase(Phase)

The action does not belong to the current phase

MustDrawFromStock

After both players pass the upcard, the first draw must come from the stock

NotInHand(Card)

The card is not in the acting player’s hand

DiscardJustTaken(Card)

The card was taken from the discard pile this turn

TooMuchDeadwood

The arrangement’s deadwood exceeds the knock limit

Fields

deadwood: u8

The deadwood of the offered arrangement

limit: u8

The knock limit in effect

MeldsMismatch

The melds do not arrange the knocker’s remaining hand

NotBigGin

The hand is not fully melded

BigGinDisabled

Big gin is disabled by the rules

NoSuchMeld(usize)

No meld at this index in the spread

CannotLayOff(Card)

The card extends no end of the meld

impl Eq for RoundError

impl Error for RoundError

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 Hash for RoundError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RoundError

fn eq(&self, other: &RoundError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
