Split 'rocket_contrib' into distinct crates. 

This follows the completed graduation of stable contrib features into
core, removing 'rocket_contrib' in its entirety in favor of two new
crates. These crates are versioned independently of Rocket's core
libraries, allowing upgrades to dependencies without consideration for
versions in core libraries.

'rocket_dyn_templates' replaces the contrib 'templates' features. While
largely a 1-to-1 copy, it makes the following changes:

  * the 'tera_templates' feature is now 'tera'
  * the 'handlebars_templates' feature is now 'handlebars'
  * fails to compile if neither 'tera' nor 'handlebars' is enabled

'rocket_sync_db_pools' replaces the contrib 'database' features. It
makes no changes to the replaced features except that the `database`
attribute is properly documented at the crate root.

## Building and Testing
### Core and Contrib
The `core` directory contains the three core libraries: `lib`, `codegen`, and
`http`. The `contrib` directory contains officially supported community
contributions and similarly consists of `lib` and `codegen`.
`http` published as `rocket`, `rocket_codegen` and `rocket_http`, respectively.
The latter two are implementations details and are reexported from `rocket`.
Public APIs are exposed via `lib` packages: `core/lib` is distributed as the
`rocket` crate while `contrib/lib` is distributed as the `rocket_contrib` crate.
The remaining crates are implementation details.
### Library Testing
### Testing
Rocket's complete test suite can be run with `./scripts/test.sh` from the root

This crate adds support for dynamic template rendering to Rocket. It
automatically discovers templates, provides a `Responder` to render templates,
and automatically reloads templates when compiled in debug mode. At present, it
supports [Handlebars] and [Tera].
[Tera]: https://docs.rs/crate/tera/1
[Handlebars]: https://docs.rs/crate/handlebars/3
# Usage
1. Enable the `rocket_dyn_templates` feature corresponding to your templating
engine(s) of choice:
```toml
[dependencies.rocket_dyn_templates]
version = "0.1.0-dev"
default-features = false
features = ["handlebars", "tera"]
```
1. Write your template files in Handlebars (`.hbs`) and/or Tera (`.tera`) in
the configurable `template_dir` directory (default:
`{rocket_root}/templates`).
2. Attach `Template::fairing()` and return a `Template` using
`Template::render()`, supplying the name of the template file **minus the
last two extensions**:
```rust
use rocket_dyn_templates::Template;
#[launch]
fn rocket() -> _ {
rocket::build().attach(Template::fairing())
}
#[get("/")]
fn index() -> Template {
Template::render("template-name", &context)
}
```

//! This crate contains officially sanctioned contributor libraries that provide

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

//!
//! Each module in this library is held behind a feature flag, with the most

//!
//! * [handlebars_templates](templates) - Handlebars Templating
//! * [tera_templates](templates) - Tera Templating
//! * [${database}_pool](databases) - Database Configuration and Pooling
//!
//! The recommend way to include features from this crate via Rocket 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 `tera_templates` module, you
//! would add:
//!
//! ```toml
//! [dependencies.rocket_contrib]
//! version = "0.5.0-dev"
//! default-features = false
//! features = ["tera_templates"]
//! ```
//!

# `sync_db_pools` [![ci.svg]][ci] [![crates.io]][crate] [![docs.svg]][crate docs]
[crates.io]: https://img.shields.io/crates/v/rocket_sync_db_pools.svg
[crate]: https://crates.io/crates/rocket_sync_db_pools
[docs.svg]: https://img.shields.io/badge/web-master-red.svg?style=flat&label=docs&colorB=d33847
[crate docs]: https://api.rocket.rs/master/rocket_sync_db_pools
[ci.svg]: https://github.com/SergioBenitez/Rocket/workflows/CI/badge.svg
[ci]: https://github.com/SergioBenitez/Rocket/actions
This crate provides traits, utilities, and a procedural macro for configuring
and accessing database connection pools in Rocket. This implementation is backed
by [`r2d2`] and exposes connections through request guards.
[`r2d2`]: https://docs.rs/r2d2
## Usage
First, enable the feature corresponding to your database type:
```toml
[dependencies.rocket_sync_db_pools]
version = "0.1.0-dev"
default-features = false
features = ["diesel_sqlite_pool"]
```
A full list of supported databases and their associated feature names is
available in the [crate docs]. In whichever configuration source you choose,
configure a `databases` dictionary with a key for each database, here
`sqlite_logs` in a TOML source:
```toml
[default.databases]
sqlite_logs = { url = "/path/to/database.sqlite" }
```
In your application's source code:
```rust
#[macro_use] extern crate rocket;
use rocket_sync_db_pools::{database, diesel};
#[database("sqlite_logs")]
struct LogsDbConn(diesel::SqliteConnection);
#[get("/logs/<id>")]
async fn get_logs(conn: LogsDbConn, id: usize) -> Result<Logs> {
conn.run(|c| Logs::by_id(c, id)).await
}
#[launch]
fn rocket() -> _ {
rocket::build().attach(LogsDbConn::fairing())
}
```
See the [crate docs] for full details.
