# OCaml Routes Library DSL

## The `@-->` Operator

The `@-->` operator is from the `routes` library and is used to bind route patterns to handler functions.

### Example:
```ocaml
`GET, (s "posts" /? nil) @--> Handler.get_posts
```

### Breaking it down:
- `s "posts"` - matches the string "posts" in the URL path
- `/?` - path concatenation operator 
- `nil` - end of path (no more segments)
- `@-->` - "maps to" operator that binds the route to the handler

So `(s "posts" /? nil) @--> Handler.get_posts` means "the route `/posts` maps to the `Handler.get_posts` function".

### Other common operators in the routes library:
- `/:` for path parameters (e.g., `s "user" /: int /? nil` matches `/user/123`)
- `//` for wildcard paths
- `<$>` for transforming matched values

It's a DSL (domain-specific language) for expressing routes in a concise, type-safe way.
