 This application is a PasteBin clone written in Rust, powered by Actix-web.
 It is designed primarily to be used via the `curl` command, although it works
 from a browser too. Pastes are deleted when they are 30 days old (since last
 modification).

 Accepted requests are:

 POST /
     Accepts raw data in the body of the request and responds with the View and
     Edit URLs of the resulting paste. The Edit URL simply includes the edit key
     as part of the URL (see DELETE and PUT below).
     - Yields a 403 Bad Request if the paste is not valid UTF-8, or if it is
       larger than 2 MB.

     $ echo "hello world" | curl --data-binary @- http://0x3c.net
     View URL: http://0x3c.net/vxcRz
     Edit URL: http://0x3c.net/vxcRz/a7772362cf6e2c36


 GET /<id>/<?ext>
     Retrieves the content for the paste associated with <id>. If the optional
     parameter <ext> is supplied, syntax highlighting associated with the file
     extension <ext> is applied to the result (either via HTML or terminal
     escape codes, depending on whether you accept text/html).
     - Yields a 404 Not Found if <id> does not exist
     - Yields a 403 Bad Request if <ext> is an unknown file extension.

     $ curl http://0x3c.net/vxcRz
     hello world
     $ curl http://0x3c.net/vxcRz/rs
     hello world [with Rust syntax highlighting]


 DELETE /<id>/<key>
     Deletes the paste associated with <id>, provided that <key> is valid.
     - Yields a 403 Bad Request if the paste does not exist, or if the key is
       invalid.

     $ curl -X DELETE http://0x3c.net/vxcRz/a7772362cf6e2c36
     Paste Deleted.


 PUT /<id>/<key>
     Replaces the contents of the paste associated with <id>, provided that
     <key> is valid.
     - Yields a 403 Bad Request if the paste does not exist, or if the key is
       invalid, or is larger than 2 MB.

     $ echo "other world" | curl -X PUT --data-binary @- \
     > http://0x3c.net/vxcRz/a7772362cf6e2c36
     http://0x3c.net/vxcRz overwritten.
