Kutil

Rust utilities collection.

The word “kutil” means “do-it-yourselfer” in Czech.

Highlights:

• cli:
  • Handle exit codes in main()
  • Clap helpers
  • Initialize logging (via tracing)
• http:
  • Easy access to headers
  • Conditional HTTP and content negotiation
  • Read body into bytes
• io:
  • Adapters and utilities for Read, Stream, and Tokio’s AsyncRead
  • IP address discovery for servers (dual-stack IPv6 and IPv4)
• std:
  • Fostering
  • Error accumulation
  • Fast collections
  • Iterators, futures, and more
• transcoding:
  • Async encoding/decoding for popular web compression formats
