Crate rocket_contrib

Expand description

This crate contains officially sanctioned contributor libraries that provide functionality commonly used by Rocket applications.

These libraries are always kept in-sync with the core Rocket library. They provide common, but not fundamental, abstractions to be used by Rocket applications.

Each module in this library is held behind a feature flag, with the most common modules exposed by default. The present feature list is below, with an asterisk next to the features that are enabled by default:

The recommend way to include features from this crate via Cargo in your project is by adding a [dependencies.rocket_contrib] section to your Cargo.toml file, setting default-features to false, and specifying features manually. For example, to use the JSON module, you would add:

version = "0.4.11"
default-features = false
features = ["json"]

This crate is expected to grow with time, bringing in outside crates to be officially supported by Rocket.
