ch9.2 : outdated error quoted

seen here https://doc.rust-lang.org/stable/book/second-edition/ch09-02-recoverable-errors-with-result.html EDIT: or scroll up 4 lines from this: https://doc.rust-lang.org/stable/book/second-edition/ch09-02-recoverable-errors-with-result.html#matching-on-different-errors
as:

thread 'main' panicked at 'There was a problem opening the file: Error { repr:
Os { code: 2, message: "No such file or directory" } }', src/main.rs:9:12

but actual error, currently, is:

thread 'main' panicked at 'There was a problem opening the file: Os { code: 2, kind: NotFound, message: "No such file or directory" }', src/main.rs:9:13

Side note:

The error doesn't include the name of the file, so I imagine this will be hell to track down if the error is just propagated upwards. Oh actually, I do remember one example I've encountered: lukaslueg/built#14

there are 2 more such outdated errors on that page, just search for thread 'main' panicked at to find them.

The second edition of the book is using Rust 1.21.0 for the purposes of the printed version. Is that the version you're using?

I guess not. I only hit the Play button on the example which means playground is using latest stable:

rustc 1.25.0 (84203cac6 2018-03-25)
binary: rustc
commit-hash: 84203cac67e65ca8640b8392348411098c856985
commit-date: 2018-03-25
host: x86_64-unknown-linux-gnu
release: 1.25.0
LLVM version: 6.0

My bad then, closing :)
Thanks!
