Struct WithdrawalQueue

pub struct WithdrawalQueue { /* private fields */ }

Implementations

impl WithdrawalQueue

pub fn new(prefix: impl IntoStorageKey) -> Self

pub fn len(&self) -> u32

pub fn is_empty(&self) -> bool

pub fn get(&self, account_id: &AccountId) -> Option<BorrowAssetAmount>

pub fn contains(&self, account_id: &AccountId) -> bool

pub fn peek(&self) -> Option<(AccountId, BorrowAssetAmount)>

pub fn try_lock( &mut self, ) -> Result<(AccountId, BorrowAssetAmount), WithdrawalQueueLockError>

Errors

• If the queue is already locked.
• If the queue is empty.

pub fn unlock(&mut self)

pub fn try_pop(&mut self) -> Option<(AccountId, BorrowAssetAmount)>

Only pops if:

1. Queue is non-empty.
2. Queue is locked.

Unlocks the queue.

pub fn remove(&mut self, account_id: &AccountId) -> Option<BorrowAssetAmount>

If the queue is locked, accounts can only be removed if they are not at the head of the queue.

pub fn insert_or_update( &mut self, account_id: &AccountId, amount: BorrowAssetAmount, )

pub fn iter(&self) -> WithdrawalQueueIter<'_>

pub fn get_status(&self) -> WithdrawalQueueStatus

pub fn get_request_status( &self, account_id: &AccountId, ) -> Option<WithdrawalRequestStatus>

Trait Implementations

impl BorshDeserialize for WithdrawalQueue

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 WithdrawalQueue

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

impl Debug for WithdrawalQueue

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

Formats the value using the given formatter.

impl<'a> IntoIterator for &'a WithdrawalQueue

type IntoIter = WithdrawalQueueIter<'a>

Which kind of iterator are we turning this into?

type Item = (AccountId, FungibleAssetAmount<BorrowAsset>)

The type of the elements being iterated over.

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
