Struct holochain_core::context::Context

pub struct Context {
    pub agent: Agent,
    pub logger: Arc<Mutex<Logger>>,
    pub persister: Arc<Mutex<Persister>>,
    pub action_channel: SyncSender<ActionWrapper>,
    pub observer_channel: SyncSender<Observer>,
    pub file_storage: FilesystemStorage,
    pub eav_storage: EavFileStorage,
    // some fields omitted
}

Context holds the components that parts of a Holochain instance need in order to operate. This includes components that are injected from the outside like logger and persister but also the store of the instance that gets injected before passing on the context to inner components/reducers.

Fields

agent: Agent

logger: Arc<Mutex<Logger>>

persister: Arc<Mutex<Persister>>

action_channel: SyncSender<ActionWrapper>

observer_channel: SyncSender<Observer>

file_storage: FilesystemStorage

eav_storage: EavFileStorage

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
