BigHexToBigDecimal - Given a hex encoded big number, converts it to decimal big integer.

BigHexToBigFloat - Converts hex encoded big integer to big floating point number @note To be used for better precision flaoting point arithmetic.

BigIntToBigFloat - Given big number, attempts to convert it to big floating point number.

CleanSlice - When we're done using one slice of txs, it's better to clean those up, so that it becomes eligible for GC.

FromMessagePack - Given serialized byte array, attempts to deserialize into structured tx format.

HexToDecimal - Converts hex encoded uint64 to decimal string.

HumanReadableGasPrice - Returns gas price paid for tx in Gwei unit.

Insert - Insert tx into slice of sorted mempool txs, while keeping it sorted If more memory allocation is required for inserting new element, it'll be done & new slice to be returned.

IsPresentInCurrentPool - Given tx hash, which was previously present in pending/ queued pool attempts to check whether it's present in current txpool content or not @note `txs` is current pending/ queued pool state received over RPC interface.

NumericGasPriceGwei - GasPrice in Gwei unit represented as floating point ( double precision ).

Remove - Removes existing entry from sorted slice of txs.

TrackNotFoundTxs - Those tx(s) which are found to be mined before actual pending tx is added into mempool, are kept track of here & pending pool pruner is informed about it, when it's found to be joining mempool, in some time future.

UntilNonceGap - Returns subslice of txs, where no nonce-gap exists for `> nonce + 1`.

Sorting direction representation.

When submitting async request for pruning pending/ queued pool, immediate response to be sent to client in any of these form(s).

When submitting async request for pruning pending/ queued pool, immediate response to be sent to client in any of these form(s).

AddRequest - For adding new tx into pool.

ConfirmedTx - When we learn a certain tx has been confirmed by listening to blocks getting mined, we'll attempt to dequeue any stuck tx from queued pool & put it into pending pool.

CountRequest - Getting #-of txs present in pool.

ExistsRequest - Checking whether tx is present in pool or not.

GetRequest - Obtaining reference to existing tx in pool.

LastSeenBlock - Which block number was last seen by header subscriber along with time.

ListRequest - Listing all txs in pool.

MemPool - Current state of mempool, where all pending/ queued tx(s) are present.

MemPoolTx - This is how tx is placed in mempool, after performing RPC call for fetching currently pending/ queued tx(s) in mempool it'll be destructured into this format, for further computation.

Msg - Response message sent to client.

NewSeenBlock - When new block is seen by header listener, concurrent-safe updation is sent to pending pool worker.

PendingPool - Currently present pending tx(s) i.e.

QueuedPool - Currently present queued tx(s) i.e.

RemovedUnstuckTx - Remove unstuck tx from queued pool, request to be sent in this form.

RemoveRequest - For removing existing tx into pool.

RemoveTxsRequest - For checking which txs can be removed from pending pool, this request to be sent to pending pool manager.

RemoveTxsFromQueuedPool - For updating local queued pool state, request of this form to be sent to pool manager over channel, where it'll check which txs are likely to be unstuck & has moved to pending pool.

Resource - Shared resources among multiple go routines Needs to be released carefully when shutting down.

Stat - Response to client queries for current mempool state to be sent in this form.

TxsFromARequest - When requesting for txs living in pool sent from some specific address, use this construct.

TxStatus - When ever multiple go routines need to concurrently fetch status of tx, given hash they will communicate back to caller using this data structure, where `status` denotes result of intended check, which was performed concurrently @note Data to be sent in this form over communication channel.

MemPoolTxsAsc - List of mempool tx(s) @note This structure to be used for sorting tx(s) in ascending way, using gas price they're paying.

MemPoolTxsDesc - List of mempool tx(s) @note This structure to be used for sorting tx(s) in descending way, using gas price they're paying.

TxsFromAddressAsc - List of txs, sent from same address sorted by their nonce.
