Types

type PostgresPoolStorage

type PostgresPoolStorage struct {
	// contains filtered or unexported fields
}

PostgresPoolStorage is an implementation of the Pool interface that uses a postgres database to store the data

func NewPostgresPoolStorage

func NewPostgresPoolStorage(cfg db.Config) (*PostgresPoolStorage, error)

NewPostgresPoolStorage creates and initializes an instance of PostgresPoolStorage

func (*PostgresPoolStorage) AddTx

func (p *PostgresPoolStorage) AddTx(ctx context.Context, tx pool.Transaction) error

AddTx adds a transaction to the pool table with the provided status

func (*PostgresPoolStorage) CountTransactionsByStatus

func (p *PostgresPoolStorage) CountTransactionsByStatus(ctx context.Context, status pool.TxStatus) (uint64, error)

CountTransactionsByStatus get number of transactions accordingly to the provided status

func (*PostgresPoolStorage) DeleteTxsByHashes

func (p *PostgresPoolStorage) DeleteTxsByHashes(ctx context.Context, hashes []common.Hash) error

DeleteTxsByHashes deletes txs by their hashes

func (*PostgresPoolStorage) GetGasPrice

func (p *PostgresPoolStorage) GetGasPrice(ctx context.Context) (uint64, error)

GetGasPrice returns the current gas price

func (*PostgresPoolStorage) GetNonce

func (p *PostgresPoolStorage) GetNonce(ctx context.Context, address common.Address) (uint64, error)

GetNonce gets the nonce to the provided address accordingly to the txs in the pool

func (*PostgresPoolStorage) GetPendingTxHashesSince

func (p *PostgresPoolStorage) GetPendingTxHashesSince(ctx context.Context, since time.Time) ([]common.Hash, error)

GetPendingTxHashesSince returns the pending tx since the given time.

func (*PostgresPoolStorage) GetTxByHash

func (p *PostgresPoolStorage) GetTxByHash(ctx context.Context, hash common.Hash) (*pool.Transaction, error)

GetTxByHash gets a transaction in the pool by its hash

func (*PostgresPoolStorage) GetTxFromAddressFromByHash

func (p *PostgresPoolStorage) GetTxFromAddressFromByHash(ctx context.Context, hash common.Hash) (common.Address, uint64, error)

GetTxFromAddressFromByHash gets tx from address by hash

func (*PostgresPoolStorage) GetTxs

func (p *PostgresPoolStorage) GetTxs(ctx context.Context, filterStatus pool.TxStatus, isClaims bool, minGasPrice, limit uint64) ([]*pool.Transaction, error)

GetTxs gets txs with the lowest nonce

func (*PostgresPoolStorage) GetTxsByFromAndNonce

func (p *PostgresPoolStorage) GetTxsByFromAndNonce(ctx context.Context, from common.Address, nonce uint64) ([]pool.Transaction, error)

GetTxsByFromAndNonce get all the transactions from the pool with the same from and nonce

func (*PostgresPoolStorage) GetTxsByStatus

func (p *PostgresPoolStorage) GetTxsByStatus(ctx context.Context, status pool.TxStatus, isClaims bool, limit uint64) ([]pool.Transaction, error)

GetTxsByStatus returns an array of transactions filtered by status limit parameter is used to limit amount txs from the db, if limit = 0, then there is no limit
