The most low-level, raw type representing an asynchronous, possibly side-effecting operation that yields a
value of type T as a result.
The most low-level, raw type representing an asynchronous, possibly side-effecting operation that yields a
value of type T as a result.
Async is a consumer of a callback. When a callback is passed to Async, it should start the operation
and ultimately notify the callback about the result. Each time the callback is passed, the
entire operation should be repeated, involving all possible side effects. Operation should never be started
without the callback being passed (i.e. there should be no observable side effects before a callback is passed).
Implementation of Async should also be prepared to accept a callback before the previous one was notified
about the result (i.e. it should support concurrent execution).
A callback that gets notified when value of type T gets computed or when computation of that value fails.
A callback that gets notified when value of type T gets computed or when computation of that value fails.
Callbacks should never throw exceptions. Preferably, they should be simple notifiers that delegate the real
work somewhere else, e.g. schedule some handling code on a separate executor
(e.g. ExecutionContext).
Raw type of an operation that executes a RestRequest.
Raw type of an operation that executes a RestRequest. The operation should be run every time the
resulting Async value is passed a callback. It should not be run before that. Each run may involve side
effects, network communication, etc. Runs may be concurrent.
Request handlers should never throw exceptions but rather convert them into failing implementation of
Async. One way to do this is by wrapping the handler with safeHandle.
Similar to HandleRequest but accepts already resolved path as a second argument.
Ensures that all possible exceptions thrown by a request handler are not propagated but converted into
an instance of Async that notifies its callbacks about the failure.
