Development Notes

CI uses "whatever the stable rustfmt is" and you'll experience a lot of friction if you drift from that.

Releasing

Remove -dev from the version in gotham/Cargo.toml
Remove -dev from the version in gotham_derive/Cargo.toml
Update the #![doc(html_root_url)] to point to the new version.
Make a commit of the release with a message like Releasing v0.x
Tag the commit as gotham_derive-0.x
Tag the commit as gotham-0.x
Create a branch for 0.x-maint
mv Cargo.toml Cargo.toml.suspend - the workspace has patches that interfere with releasing.
pushd gotham_derive; cargo publish; popd
pushd gotham; cargo publish; popd
Change the version in gotham/Cargo.toml to 0.<x+1>-dev
Change the version in gotham_derive/Cargo.toml to 0.<x+1>-dev
Commit with a message like Starting v0.<x+1>-dev
Push the commits and tags
Change to the maint branch and push that.
Start announcing the release.
