Enum BidState 

#[repr(C)]
pub enum BidState {
    EnglishAuction {
        bids: Vec<Bid>,
        max: usize,
    },
    OpenEdition {
        bids: Vec<Bid>,
        max: usize,
    },
}

BidState tracks the running state of an auction, each variant represents a different kind of auction being run.

Implementations

impl BidState

Bidding Implementations.

English Auction: this stores only the current winning bids in the auction, pruning cancelled and lost bids over time.

Open Edition: All bids are accepted, cancellations return money to the bidder and always succeed.

pub fn new_english(n: usize) -> Self

pub fn new_open_edition() -> Self

pub fn max_array_size_for(n: usize) -> usize

pub fn place_bid( &mut self, bid: Bid, tick_size: Option<u64>, gap_tick_size_percentage: Option<u8>, minimum: u64, instant_sale_price: Option<u64>, auction_state: &mut AuctionState, ) -> Result<(), ProgramError>

Push a new bid into the state, this succeeds only if the bid is larger than the current top winner stored. Crappy list information to start with.

pub fn cancel_bid(&mut self, key: Pubkey) -> Result<(), ProgramError>

Cancels a bid, if the bid was a winning bid it is removed, if the bid is invalid the function simple no-ops.

pub fn amount(&self, index: usize) -> u64

pub fn is_winner(&self, key: &Pubkey, min: u64) -> Option<usize>

Check if a pubkey is currently a winner and return winner #1 as index 0 to outside world.

pub fn num_winners(&self) -> u64

pub fn num_possible_winners(&self) -> u64

pub fn winner_at(&self, index: usize) -> Option<Pubkey>

Idea is to present #1 winner as index 0 to outside world with this method

pub fn lowest_winning_bid_is_instant_bid_price( &self, instant_sale_amount: u64, ) -> bool

Trait Implementations

impl BorshDeserialize for BidState

where Vec<Bid>: BorshDeserialize, usize: BorshDeserialize,

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

impl BorshSerialize for BidState

where Vec<Bid>: BorshSerialize, usize: BorshSerialize,

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for BidState

fn clone(&self) -> BidState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BidState

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

Formats the value using the given formatter.

impl PartialEq for BidState

fn eq(&self, other: &BidState) -> 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.
