〰️ pantrace

Coverage crates.io docs.rs Tests

Pantrace converts between traceroute formats, in the same way as Pandoc converts between document formats.

Each format needs to implement only two conversions: to and from the internal format.

Quickstart

Cargo

cargo install pantrace && pantrace --help

Docker

docker run ghcr.io/dioptra-io/pantrace:main --help

Nix

nix run github:dioptra-io/pantrace -- --help

Usage

# Fetch traceroute results from the RIPE Atlas API
curl -L -o example.ndjson \
    "https://atlas.ripe.net/api/v2/measurements/23119199/results/?start=1625097600&stop=1625788799&format=txt&probe_ids=6479"
  
# Convert from the standard input to the standard output
cat example.ndjson | pantrace --standalone --from atlas --to scamper-trace-warts > example.warts

# Convert from a file to a file
pantrace --standalone --from atlas --to scamper-trace-warts --input example.ndjson --output example.warts

Formats

  • atlas: RIPE Atlas JSONL (read/write)
  • flat: JSONL with one document per reply (write-only)
  • internal: Pantrace internal format (read/write)
  • iris: Iris JSONL format (read/write)
  • scamper-trace-warts: Scamper traceroute in warts format (read/write)

Implementing a new format

To add a new CustomFormat to the pantrace CLI (main.rs), two structures must be implemented:

  • CustomTracerouteReader which implements the Iterator<Item = Result<Traceroute>> trait.
  • CustomTracerouteWriter which implements the TracerouteWriter trait, and in particular the fn write_traceroute(&mut self, traceroute: &Traceroute) -> Result<()> function where Traceroute is pantrace's internal traceroute format.

The conversion between CustomFormat and Traceroute can be implemented in any way, but the current formats are implemented as follows:

  • CustomFormat to Traceroute conversion in a to_internal module:
    • impl From<CustomFormat> for Traceroute { ... }
  • CustomFormat from Traceroute conversion in a from_internal module
    • impl From<Traceroute> for CustomFormat { ... }
    • or impl From<Traceroute> for Vec<CustomFormat> { ... } if CustomFormat is a single path traceroute format
