# kudu-rs

bind kudu version 1.7.1

Experimental Rust bindings for Apache Kudu (incubating). Not feature complete.

[Documentation](https://danburkert.github.io/kudu-rs/kudu/index.html)


# build
do not use rust stable version to build. 

because prost-derive = "0.4" at stable rust version got error:

```
^^^^^^^^^^^ multiple `intersperse` found
```

so,try with 


```bash
cargo +nightly build
```

You will need to add `kudu-master` and `kudu-tserver` to the $PATH, or set
`$KUDU_HOME` to your checkout of the kudu repository, and build Kudu in
`$KUDU_HOME/build/latest` (see the Kudu [build from source
instructions](http://getkudu.io/docs/installation.html#_build_from_source)).

```bash
env KUDU_HOME=<path-to-kudu-checkout> cargo build
```

A 306 HDI may continue to run after you switch off the engine if the ignition timing is set improperly. This will force the engine to continue running for several seconds.
Why does your car stop running when the key is released?
If the engine stops running when the key is released, then the ignition switch is probably bad. The switch will need to be replaced.
Why does freightliner truck engine keep running with key turned off?
What is the function of a stop switch in a motorbike?
The function of a stop switch is to cut the ignition so the engine can stop. If the switch is in the off position and the engine isn't running, then to start the bike you'll have to put it to the on position.
Why would the AC and turn signals work when the engine is off but not when it is running?
Most likely is a bad ignition switch.
What causes ignition switch to not turn an engine over?
A bad connection inside the ignition switch will keep it from turning the engine over.
Probably a stuck solenoid.
2001 dodge caravan and your it was stolen and there was damage to the ignition area and now the engine will not stay running is there a kill switch?
Not a switch, but you could have a problem with the Sentry Key System. The key has a chip in it that communicates with a receiver near the ignition switch. You will have to go to a dealer for service.
How can you use the radio or CD player without running the engine on a 2007 Peugeot 307?
Key turns will not start it is like the safety switch on the clutch is not engageing any suggestions?
several could bes. If there is no action, the engine does not turn, the rod running from the key switch to the ignition switch
