@kornelski thanks for the PR! seems like the 1.36 toolchain build is failing on the env_logger upgrade - see Travis. #[non_exhaustive] was stabilized in 1.40 as far as I see.

at this point I wouldn't have anything against increasing the min. supported toolchain to 1.40, which implies:

• Changing all occurences of 1.36 in the README.md and travis.yml
• Re-running clippy for the new min. supported toolchain: rustup run --install 1.40.0 cargo clippy --lib --tests --all-features -- -D clippy::pedantic -D clippy::nursery

alternatively you could also find an env_logger version that works with 1.36.

It's failing on pedantic clippy lints, which are turned into errors. I don't think it's a good idea to treat every pedantic suggestion (many of which are meaningless or wrong) as stop-the-build catastrophic error.

feel free to disable the pedantic check in Travis (also in the README please), I know it can be a pain.

Ok, I've managed to make it a proper Travis Job.

@kornelski thanks! the Travis jobs look lovely, though I trimmed some things down in #136
