}

type BorBlockLogsFilter 

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

BorBlockLogsFilter can be used to retrieve and filter logs.

func NewBorBlockLogsFilter 

func NewBorBlockLogsFilter(backend Backend, borConfig *params.BorConfig, block common.Hash, addresses []common.Address, topics [][]common.Hash) *BorBlockLogsFilter

NewBorBlockLogsFilter creates a new filter which directly inspects the contents of a block to figure out whether it is interesting or not.

func NewBorBlockLogsRangeFilter 

func NewBorBlockLogsRangeFilter(backend Backend, borConfig *params.BorConfig, begin, end int64, addresses []common.Address, topics [][]common.Hash) *BorBlockLogsFilter

NewBorBlockLogsRangeFilter creates a new filter which uses a bloom filter on blocks to figure out whether a particular block is interesting or not.

func (*BorBlockLogsFilter) Logs 

func (f *BorBlockLogsFilter) Logs(ctx context.Context) ([]*types.Log, error)

Logs searches the blockchain for matching log entries, returning all from the first block that contains matches, updating the start of the filter accordingly.

type EventSystem 

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

EventSystem creates subscriptions, processes events and broadcasts them to the subscription which match the subscription criteria.

func NewEventSystem 

func NewEventSystem(backend Backend, lightMode bool) *EventSystem

NewEventSystem creates a new manager that listens for event on the given mux, parses and filters them. It uses the all map to retrieve filter changes. The work loop holds its own index that is used to forward events to filters.

The returned manager has a loop that needs to be stopped with the Stop function or by stopping the given mux.

func (*EventSystem) SubscribeLogs 

func (es *EventSystem) SubscribeLogs(crit ethereum.FilterQuery, logs chan []*types.Log) (*Subscription, error)

SubscribeLogs creates a subscription that will write all logs matching the given criteria to the given logs channel. Default value for the from and to block is "latest". If the fromBlock > toBlock an error is returned.

}

Filter can be used to retrieve and filter logs.

func NewBlockFilter

NewRangeFilter creates a new filter which uses a bloom filter on blocks to figure out whether a particular block is interesting or not.

func (*Filter) Logs 

func (f *Filter) Logs(ctx context.Context) ([]*types.Log, error)

Logs searches the blockchain for matching log entries, returning all from the first block that contains matches, updating the start of the filter accordingly.

type FilterCriteria

type PublicFilterAPI 

type PublicFilterAPI struct {
	// contains filtered or unexported fields

PublicFilterAPI offers support to create and manage filters. This will allow external clients to retrieve various information related to the Ethereum protocol such als blocks, transactions and logs.

func NewPublicFilterAPI 

func NewPublicFilterAPI(backend Backend, lightMode bool, timeout time.Duration, borLogs bool) *PublicFilterAPI

NewPublicFilterAPI returns a new PublicFilterAPI instance.

For pending transaction and block filters the result is []common.Hash. (pending)Log filters return []Log.

https://eth.wiki/json-rpc/API#eth_getfilterchanges

func (*PublicFilterAPI) GetFilterLogs 

func (api *PublicFilterAPI) GetFilterLogs(ctx context.Context, id rpc.ID) ([]*types.Log, error)

GetFilterLogs returns the logs for the filter with the given id. If the filter could not be found an empty array of logs is returned.

https://eth.wiki/json-rpc/API#eth_getfilterlogs

func (*PublicFilterAPI) GetLogs 

func (api *PublicFilterAPI) GetLogs(ctx context.Context, crit FilterCriteria) ([]*types.Log, error)

GetLogs returns logs matching the given argument that are stored within the state.

https://eth.wiki/json-rpc/API#eth_getlogs

func (*PublicFilterAPI) Logs 

func (api *PublicFilterAPI) Logs(ctx context.Context, crit FilterCriteria) (*rpc.Subscription, error)

Logs creates a subscription that fires for all new log that match the given filter criteria.

func (*PublicFilterAPI) NewBlockFilter 

func (api *PublicFilterAPI) NewBlockFilter() rpc.ID

NewBlockFilter creates a filter that fetches blocks that are imported into the chain. It is part of the filter package since polling goes with eth_getFilterChanges.

https://eth.wiki/json-rpc/API#eth_newblockfilter

func (*PublicFilterAPI) NewDeposits 

func (api *PublicFilterAPI) NewDeposits(ctx context.Context, crit ethereum.StateSyncFilter) (*rpc.Subscription, error)

NewDeposits send a notification each time a new deposit received from bridge.

func (*PublicFilterAPI) NewFilter 

func (api *PublicFilterAPI) NewFilter(crit FilterCriteria) (rpc.ID, error)

NewFilter creates a new filter and returns the filter id. It can be used to retrieve logs when the state changes. This method cannot be used to fetch logs that are already stored in the state.

Default criteria for the from and to block are "latest". Using "latest" as block number will return logs for mined blocks. Using "pending" as block number returns logs for not yet mined (pending) blocks. In case logs are removed (chain reorg) previously returned logs are returned again but with the removed property set to true.

In case "fromBlock" > "toBlock" an error is returned.

https://eth.wiki/json-rpc/API#eth_newfilter

func (*PublicFilterAPI) NewHeads 

func (api *PublicFilterAPI) NewHeads(ctx context.Context) (*rpc.Subscription, error)

NewHeads send a notification each time a new (header) block is appended to the chain.

func (*PublicFilterAPI) NewPendingTransactionFilter 

func (api *PublicFilterAPI) NewPendingTransactionFilter() rpc.ID

NewPendingTransactionFilter creates a filter that fetches pending transaction hashes as transactions enter the pending state.

It is part of the filter package because this filter can be used through the `eth_getFilterChanges` polling method that is also used for log filters.

https://eth.wiki/json-rpc/API#eth_newpendingtransactionfilter

func (*PublicFilterAPI) NewPendingTransactions 

func (api *PublicFilterAPI) NewPendingTransactions(ctx context.Context) (*rpc.Subscription, error)

SetChainConfig sets chain config

func (*PublicFilterAPI) UninstallFilter 

func (api *PublicFilterAPI) UninstallFilter(id rpc.ID) bool

UninstallFilter removes the filter with the given filter id.

https://eth.wiki/json-rpc/API#eth_uninstallfilter

type Subscription 

type Subscription struct {
	ID rpc.ID
	// contains filtered or unexported fields
}

Subscription is created when the client registers itself for a particular event.

func (*Subscription) Err 

func (sub *Subscription) Err() <-chan error

Err returns a channel that is closed when unsubscribed.
