Values

debug_state

pub fn debug_state(a: List(DebugOption)) -> DebugState

get_state

</>

pub fn get_state(from from: process.Pid) -> dynamic.Dynamic

Get the state of a given OTP compatible process. This function is only intended for debugging.

Requires Erlang/OTP 26.1 or newer, as the underlying interface changed in OTP-18633 from a literal type to a result type.

For more information see the Erlang documentation.

resume

pub fn resume(pid: process.Pid) -> Nil

Request a suspended OTP compatible process to result, causing it to handle all messages rather than only system messages.

For more information see the Erlang documentation.

suspend

</>

pub fn suspend(pid: process.Pid) -> Nil

Request an OTP compatible process to suspend, causing it to only handle system messages.

For more information see the Erlang documentation.
