Struct WithdrawingState

pub struct WithdrawingState {
    pub op_id: u64,
    pub index: u32,
    pub remaining: u128,
    pub collected: u128,
    pub receiver: AccountId,
    pub owner: AccountId,
    pub escrow_shares: u128,
}

Collecting liquidity from markets to satisfy a user withdrawal/redeem request.

Transitions:

• Advance within queue: Withdrawing (index increments) while collecting funds.
• When enough is collected to satisfy the request: Payout.
• If the op is stopped or cannot proceed and needs to refund: Idle (escrow_shares refunded).

Fields

op_id: u64

Unique operation id used to correlate async callbacks and detect drift.

index: u32

Zero-based position within the withdraw queue currently being processed.

remaining: u128

Remaining assets that must still be collected to satisfy the request.

collected: u128

Assets already collected and held as idle_balance pending payout.

receiver: AccountId

Account that should receive the assets during payout.

owner: AccountId

The owner whose shares are being redeemed.

escrow_shares: u128

Shares locked in escrow for this request.

• Refunded on stop/failure.
• On payout success, a portion is burned (see burn_shares) and any remainder is refunded.

Trait Implementations

impl AsRef<WithdrawingState> for OpState

fn as_ref(&self) -> &WithdrawingState

Converts this type into a shared reference of the (usually inferred) input type.

impl BorshDeserialize for WithdrawingState

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

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.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for WithdrawingState

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

impl Clone for WithdrawingState

fn clone(&self) -> WithdrawingState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WithdrawingState

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

Formats the value using the given formatter.

impl From<WithdrawingState> for OpState

fn from(s: WithdrawingState) -> Self

Converts to this type from the input type.

impl PartialEq for WithdrawingState

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