Enum Edge 

pub enum Edge {
    Draw,
    Fold,
    Check,
    Call,
    Open(Chips),
    Raise(Odds),
    Shove,
}

An abstracted game tree transition.

Unlike Action which carries exact chip amounts, Edge abstracts betting actions for strategy lookup across different stack depths.

Variants

• Draw — Chance node (card deal)
• Fold, Check, Call — Standard player decisions
• Open(Chips) — Preflop open in BB units (e.g., 2BB, 3BB)
• Raise(Odds) — Pot-relative raise (e.g., 1/2 pot, 2x pot)
• Shove — All-in bet

Implementations

impl Edge

pub fn is_shove(&self) -> bool

True if this is an all-in bet.

pub fn is_raise(&self) -> bool

True if this is a raise (including opens).

pub fn is_folded(&self) -> bool

True if this is a fold.

pub fn is_chance(&self) -> bool

True if this is a chance node (card deal).

pub fn is_aggro(&self) -> bool

True if this is aggressive (raise, open, or shove).

pub fn is_choice(&self) -> bool

True if this is a player decision.

impl Edge

pub fn regret(&self) -> (Utility, Utility)

Initial regret bounds for CFR warmstart.

Returns (min, max) regret to bias exploration toward certain actions.

pub fn policy(&self) -> (Probability, Probability)

Initial policy bounds (currently unused).

impl Edge

pub fn raises(street: Street, depth: usize) -> Vec<Self>

Returns available raise/open edges for a given street and depth. This is the single source of truth for which betting edges exist.

pub fn into_chips(self, pot: Chips) -> Chips

Converts edge to chip amount given pot size.

Trait Implementations

impl Arbitrary for Edge

fn random() -> Self

Generate a uniformly random instance.

impl Clone for Edge

fn clone(&self) -> Edge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Edge

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

Formats the value using the given formatter.

impl Display for Edge

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

Formats the value using the given formatter.

impl From<Action> for Edge

fn from(action: Action) -> Self

Converts to this type from the input type.

impl From<Edge> for u64

fn from(edge: Edge) -> Self

Converts to this type from the input type.

u8 bijection Layout: 1-5 = basic edges, 6-9 = Open(OPENS_GRID), 10-15 = Raise(RAISE_GRID)

fn from(edge: Edge) -> Self

Converts to this type from the input type.

impl From<Odds> for Edge

fn from(odds: Odds) -> Self

Converts to this type from the input type.

impl From<u64> for Edge

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 Ord for Edge

fn cmp(&self, other: &Edge) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self
