RTRTR: a versatile tool for route filters.
This is the library crate of RTRTR providing all real functionality.
RTRTR is designed around a concept of components being plugged together in whichever way the user likes. There are currently two types of components: units that collect, process, and forward data, and targets that make the data from a select unit available to the outside. All types of units and targets are defined in the modules units and targets, respectively.
If you are trying to get started with the source code, perhaps begin with comms and continue with units before reading manager. This should give you a somewhat gentle introduction into the overall architecture.
