Cross-origin resource sharing (CORS) for Rocket applications
Rocket requires nightly Rust. You should probably install Rust with rustup, then override the code directory to use nightly instead of stable. See installation instructions.
In particular, rocket_cors is currently targetted for the latest nightly. Older nightlies might
work, but they are subject to the minimum that Rocket sets.
Add the following to Cargo.toml:
toml
rocket_cors = "0.2.2"
To use the latest master branch, for example:
toml
rocket_cors = { git = "https://github.com/lawliet89/rocket_cors", branch = "master" }
