Crash due to subtract with overflow about prettytable-rs HOT 4 CLOSED

Ha, just ran across this independently in #137. That's a fix for it, in any case.

from prettytable-rs.

Will close this when I've cut 1.0.0 hopefully today - I've merged the panic fix - fuzz tyvm!

from prettytable-rs.

I merged the fix - tyvm @5225225 - the repro instead of attempt to subtract with overflow:

$ cargo run

thread 'main' panicked at 'attempt to subtract with overflow', /home/foobar/.cargo/registry/src/github.com-1ecc6299db9ec823/prettytable-rs-0.9.0/src/utils.rs:106:5

We now get UnequalLengths unhandled error panic in repro which comes from csv crate

$ cargo run

     Running `target/debug/test-fuzz-pretty`
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error(UnequalLengths { pos: Some(Position { byte: 11, line: 2, record: 1 }), expected_len: 1, len: 2 })', src/main.rs:17:37

Adding ReaderBuilder.flexible(true) gets past that unhandled error in repro panic.

The output becames }ESCESCESC[ESC[}[ESC but no panic so works as expected now with empty table format.

Release 0.10.0 is out with this fixed 🥳
