Eth.Sentry.Event

Event Sentry - HTTP Style - Polling ftw

type EventSentry msg

type Msg

type alias Ref =

Int

init : (Msg -> msg) -> HttpProvider -> ( EventSentry msg, Cmd msg )

stopWatching : Ref -> EventSentry msg -> EventSentry msg

update : Msg -> EventSentry msg -> ( EventSentry msg, Cmd msg )

watch :

(Log -> msg)

-> EventSentry msg

-> LogFilter

-> ( EventSentry msg, Cmd msg, Ref )

Continuously polls for logs in newly mined blocks.

If the range within the LogFilter includes past blocks, then all events within the given block range are returned, along with events in the latest block.

Polling continues until stopWatching is called.

watchOnce :

(Log -> msg)

-> EventSentry msg

-> LogFilter

-> ( EventSentry msg, Cmd msg )

Returns the first log found.

If a block range is defined in the LogFilter, this will only return the first log found within that given block range.

currentBlock : EventSentry msg -> Maybe Int

The Event Sentry polls for the latest block. Might as well allow the user to see it.
