Link to this section Summary

Functions

address(pid)

Returns the current Contract GenServer’s address

at(pid, address)

Sets the current Contract GenServer’s address to given address

call(pid, method_name, args \\ [])

Use a Contract’s method with an eth_call

child_spec(arg)

Returns a specification to start this module under a supervisor

deploy(pid, args)

Deploys contracts with given arguments

deploy_helper(bin, abi, args)

eth_call_helper(address, abi, method_name, args)

eth_send_helper(address, abi, method_name, args, options)

init(state)

Invoked when the server is started. start_link/3 or start/3 will block until it returns

send(pid, method_name, args, options)

Use a Contract’s method with an eth_sendTransaction

start_link(name, state)

Begins a Contract GenServer with specified name and state

tx_receipt(pid, tx_hash)

Returns a formatted transaction receipt for the given transaction hash(id)

address(pid)

address(pid()) :: {:ok, binary()}

Returns the current Contract GenServer’s address

at(pid, address)

at(pid(), binary()) :: :ok

Sets the current Contract GenServer’s address to given address

call(pid, method_name, args \\ [])

call(pid(), keyword(), []) :: {:ok, any()}

Use a Contract’s method with an eth_call

child_spec(arg)

Returns a specification to start this module under a supervisor.

See Supervisor.

deploy(pid, args)

deploy(pid(), []) :: {:ok, []}

Deploys contracts with given arguments

deploy_helper(bin, abi, args)

eth_call_helper(address, abi, method_name, args)

eth_send_helper(address, abi, method_name, args, options)

init(state)

Invoked when the server is started. start_link/3 or start/3 will block until it returns.

args is the argument term (second argument) passed to start_link/3.

Returning {:ok, state} will cause start_link/3 to return {:ok, pid} and the process to enter its loop.

Returning {:ok, state, timeout} is similar to {:ok, state} except handle_info(:timeout, state) will be called after timeout milliseconds if no messages are received within the timeout.

Returning {:ok, state, :hibernate} is similar to {:ok, state} except the process is hibernated before entering the loop. See c:handle_call/3 for more information on hibernation.

Returning :ignore will cause start_link/3 to return :ignore and the process will exit normally without entering the loop or calling c:terminate/2. If used when part of a supervision tree the parent supervisor will not fail to start nor immediately try to restart the GenServer. The remainder of the supervision tree will be (re)started and so the GenServer should not be required by other processes. It can be started later with Supervisor.restart_child/2 as the child specification is saved in the parent supervisor. The main use cases for this are:

The GenServer is disabled by configuration but might be enabled later.
An error occurred and it will be handled by a different mechanism than the Supervisor. Likely this approach involves calling Supervisor.restart_child/2 after a delay to attempt a restart.

Returning {:stop, reason} will cause start_link/3 to return {:error, reason} and the process to exit with reason reason without entering the loop or calling c:terminate/2.
