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
```
