Struct PlayTrace 

pub struct PlayTrace {
    pub board: Board,
    pub cards: ArrayVec<Card, 52>,
}

A starting board and a sequence of cards played from it

Input to Solver::analyse_play. The two fields split the position and the play-trace cleanly:

• board is the snapshot from which analysis begins. It encodes the state at the start of a trick — possibly with up to three cards already on the table in Board::current_cards — and Board::remaining holds only the cards still in each hand. Cards from previously completed tricks are not represented individually; they are simply absent from remaining.
• cards is the play trace to replay from that snapshot, in chronological order. The first card in cards is whichever card comes after any already in board.current_cards — it does not restart the trick or repeat prior history. Each card must be legal (follow suit when possible and be held by the player on turn).

cards may span trick boundaries; DDS tracks trick completion and whose lead follows internally. The trace length may be any value from 0 to 52.

Fields

board: Board

Snapshot at the start of analysis: state at the start of the current trick, plus any 0–3 cards already played to it via Board::current_cards

cards: ArrayVec<Card, 52>

Cards played after board, in chronological order; may cross tricks

Trait Implementations

impl Clone for PlayTrace

fn clone(&self) -> PlayTrace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlayTrace

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

Formats the value using the given formatter.

impl Hash for PlayTrace

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 PlayTrace

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
