Command line tools: Implementing wc in Rust
wc
Plan for improvements in the next session
- Instead of
text.split('\n').collect::<Vec<_>>().len(); write text.split('\n').count();
- Instead of
for filename in args[1..].iter() { write for filename in std::env::args().skip(1)
- Setup CI
- Test running the command line
- return struct instead tuple of 3 usize values
- Command line flags
