//! Desync pipes provide a way to generate and process streams via a `Desync` object
//!
//! Pipes are an excellent way to interface `Desync` objects and the futures library. Piping
//! a stream into a `Desync` object is equivalent to spawning it with an executor, except
//! without the need to dedicate a thread to running it.
//!
//! There are two kinds of pipe. The `pipe_in` function creates a pipe that processes each
//! value made available from a stream on a desync object as they arrive, producing no
//! results. This is useful for cases where a `Desync` object is being used as the endpoint
//! for some data processing (for example, to insert the results of an operation into an
//! asynchronous database object).
//!
//! The `pipe` function pipes data through an object. For every input value, it produces
//! an output value. This is good for creating streams that perform some kind of asynchronous
//! processing operation or that need to access data from inside a `Desync` object.
//!
//! Here's an example of using `pipe_in` to store data in a `HashSet`:
//!
//! ```
//! # extern crate futures;
//! # extern crate desync;
//! # use std::collections::HashSet;
//! # use std::sync::*;
//! #
//! use futures::future;
//! use futures::channel::mpsc;
//! use futures::executor;
//! use futures::prelude::*;
//! # use ::desync::*;
//!
//! executor::block_on(async {
//! let desync_hashset = Arc::new(Desync::new(HashSet::new()));
//! let (mut sender, receiver) = mpsc::channel(5);
//!
//! pipe_in(Arc::clone(&desync_hashset), receiver, |hashset, value| { hashset.insert(value); future::ready(()).boxed() });
//!
//! sender.send("Test".to_string()).await.unwrap();
//! sender.send("Another value".to_string()).await.unwrap();
//! #
//! # assert!(desync_hashset.sync(|hashset| hashset.contains(&("Test".to_string()))))
//! });
//! ```

* TaskLoop allows to schedule a task function being called (optionnaly repeatedly) on the main loop,

*
* The task itself is implemented in `doTick`. It can be requested and called for single execution
* using the `tick` method.
*
* It will be assured that the task execution method (`tick`) only gets called once per main loop "tick",
* no matter how often it gets requested for execution. Execution in further ticks will be scheduled accordingly.
*
* If further execution requests have already been scheduled on the next tick, it can be checked with `hasNextTick`,

*
* The task can be scheduled as an interval repeatedly with a period as parameter (see `setInterval`, `clearInterval`).
*
* Sub-classes need to implement the `doTick` method which will effectively have the task execution routine.
*
* Further explanations:
*
* The baseclass has a `tick` method that will schedule the doTick call. It may be called synchroneously
* only for a stack-depth of one. On re-entrant calls, sub-sequent calls are scheduled for next main loop ticks.
*
* When the task execution (`tick` method) is called in re-entrant way this is detected and
* we are limiting the task execution per call stack to exactly one, but scheduling/post-poning further
* task processing on the next main loop iteration (also known as "next tick" in the Node/JS runtime lingo).

<source>Generated coins must mature 110 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>

<source>%s, you must set a rpcpassword in the configuration file:
%s
It is recommended you use the following random password:
rpcuser=phreakrpc
rpcpassword=%s
(you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions.
It is also recommended to set alertnotify so you are notified of problems;
for example: alertnotify=echo %%s | mail -s "phreak Alert" [email protected]

<source>Generated coins must mature 120 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>

The general syntax for a selector is:
selector = {[alias].}{[key]$}[field|selector]
(Parts in {} are optional, | indicates alternatives)
* Alias can be:
~ refers to the resource addressed by the
preceding parts of the selector (=last
resource)
component alias of a component of the last resource
linktable alias of a link table of the last resource
table name of a table that has a foreign key for
the last resource (auto-detect the key)
key:table same as above, but specifying the foreign key
* Key can be:
key the name of a foreign key in the last resource
context a context expression
* Field can be:
fieldname the name of a field or virtual field of the
last resource
context a context expression
A "context expression" is a name enclosed in parentheses:
(context)
During parsing, context expressions get replaced by the
string which has been configured for this name for the
last resource with:
s3db.configure(tablename, context = dict(name = "string"))
With context expressions, the same selector can be used
for different resources, each time resolving into the
specific field path. However, the field addressed must
be of the same type in all resources to form valid
queries.
If a context name can not be resolved, resolve() will
still succeed - but the S3FieldPath returned will have
colname=None and ftype="context" (=unresolvable context).
