Examples

Days supports two “example styles”:

1. Config-driven simulations (configs/*.toml) run via the CLI (cargo run -- <config>).
2. Rust examples (examples/*.rs) run via cargo run --example <name>.

Config examples

Run a config from the repo root:

RUST_LOG=info cargo run -- configs/simple.toml

Measure wall-clock time without logs:

time cargo run -- configs/simple.toml

DCQCN example (requires dcqcn and typically l2_pfc):

RUST_LOG=info cargo run --features dcqcn,l2_pfc -- configs/dcqcn_simple.toml

Rust examples

List available example binaries:

ls examples

Run one:

RUST_LOG=info cargo run --example basic

The repo currently includes examples such as basic, switch, wire, tcp, and ecn (names match the .rs filenames in examples/).
