Struct dbcrossbarlib::Context

pub struct Context { /* fields omitted */ }

Context shared by our various asynchronous operations.

Methods

impl Context

pub fn create(log: Logger) -> (Self, BoxFuture<()>)

Create a new context, and a future represents our background workers, returning () if they all succeed, or an Error as soon as one of them fails.

pub fn log(&self) -> &Logger

Get the logger associated with this context.

pub fn child<T>(&self, log_kv: OwnedKV<T>) -> Self where
    T: SendSyncRefUnwindSafeKV + 'static, 

Create a child context, adding extra slog logging context. You can create the log_kv value using slog's o! macro.

pub fn spawn_worker<W>(&self, worker: W) where
    W: Future<Item = (), Error = Error> + Send + 'static, 

Spawn an async worker in this context, and report any errors to the future returned by create.

pub fn spawn_process(&self, name: String, child: Child)

Monitor an asynchrnous child process, and report any errors or non-zero exit codes that occur.
