Struct dbcrossbarlib::Context [−][src]
Context shared by our various asynchronous operations.
Implementations
impl Context
[src]
pub fn create(log: Logger) -> (Self, BoxFuture<()>)
[src]
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
[src]
Get the logger associated with this context.
pub fn child<T>(&self, log_kv: OwnedKV<T>) -> Self where
T: SendSyncRefUnwindSafeKV + 'static,
[src]
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<Output = Result<()>> + Send + 'static,
[src]
W: Future<Output = Result<()>> + 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, mut child: Child)
[src]
Monitor an asynchrnous child process, and report any errors or non-zero exit codes that occur.
