RTLola is a runtime monitoring framework. It consists of a parser, analyzer, and interpreter for the RTLola specification language.

This library crate provides two APIs to evaluate RTLola specifications through interpretation.
If you are looking for a ready to use tool try out the `rtlola-cli` crate, which provides a command line interface to the interpreter capable of parsing csv and pcap files.

For more information on the RTLola framework make sure to visit our Website:

## The RTLola language

An example for a RTLola specification is given below:

```
input a: Int64
input b: Int64

output x := a + b
trigger x > 2
```

Evaluated on a trace given in CSV format:

```
a,b,time
0,1,0.1
2,3,0.2
4,5,0.3
```

the interpreter will produce an output similar to this:

```
rtlola-cli monitor example.spec --offline relative --csv-in example.csv 
Trigger: x > 2
Trigger: x > 2
```
