Crate ecgen 

ecgen-rs: Enumerative Combinatorics Generation

A library for generating combinatorial structures like permutations, combinations, set partitions, and binary Gray codes.

Features

• std (default): Enables standard library support and logging
• diffset: Enables difference set generation (optional)

Logging

When the std feature is enabled, you can use the logging module:

use ecgen::logging::init_logger;

init_logger();
log::info!("Application started");

Set the RUST_LOG environment variable to control log level:

RUST_LOG=debug cargo run --features std
