Trait TransactionQueue 

pub trait TransactionQueue<T>:
    Debug
    + Default
    + Extend<T>
    + Sync
    + Send {
    // Required methods
    fn is_empty(&self) -> bool;
    fn choose<R: Rng>(
        &mut self,
        rng: &mut R,
        amount: usize,
        batch_size: usize,
    ) -> Vec<T>;
    fn remove_multiple<'a, I>(&mut self, txs: I)
       where I: IntoIterator<Item = &'a T>,
             T: 'a + Contribution;
}

An interface to the transaction queue. A transaction queue is a structural part of QueueingHoneyBadger that manages enqueueing of transactions for a future batch and dequeueing of transactions to become part of a current batch.

Required Methods

fn is_empty(&self) -> bool

Checks whether the queue is empty.

fn choose<R: Rng>( &mut self, rng: &mut R, amount: usize, batch_size: usize, ) -> Vec<T>

Returns a new set of amount transactions, randomly chosen from the first batch_size. No transactions are removed from the queue.

fn remove_multiple<'a, I>(&mut self, txs: I)

where I: IntoIterator<Item = &'a T>, T: 'a + Contribution,

Removes the given transactions from the queue.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
