pub struct Instance { /* fields omitted */ }

Object representing a Holochain instance, i.e. a running holochain (DNA + DHT + source-chain) Holds the Event loop and processes it with the redux pattern.

Methods

impl Instance

pub fn default_channel_buffer_size() -> usize

pub fn action_channel(&self) -> SyncSender<ActionWrapper>

get a clone of the action channel

pub fn observer_channel(&self) -> SyncSender<Observer>

get a clone of the observer channel

pub fn dispatch(&mut self, action_wrapper: ActionWrapper)

Stack an Action in the Event Queue

Panics

Panics if called before start_action_loop.

pub fn dispatch_and_wait(&mut self, action_wrapper: ActionWrapper)

Stack an Action in the Event Queue and block until is has been processed.

Panics

Panics if called before start_action_loop.

pub fn dispatch_with_observer<F>(     &mut self,     action_wrapper: ActionWrapper,     closure: F ) where     F: 'static + FnMut(&State) -> bool + Send,

Stack an action in the Event Queue and create an Observer on it with the specified closure

Panics

Panics if called before start_action_loop.

pub fn initialize_context(&self, context: Arc<Context>) -> Arc<Context>

pub fn start_action_loop(&mut self, context: Arc<Context>)

Start the Event Loop on a seperate thread

pub fn new(context: Arc<Context>) -> Self

Creates a new Instance with disconnected channels.

pub fn from_state(state: State) -> Self
