This completes the migration of custom derives to proc-macros, removing
the need for the `custom_derive` feature in consumer code. This commit
also includes documentation, unit tests, and compile UI tests for each
of the derives.
Additionally, this commit improves the existing `FromForm` and
`FromFormValue` derives. The generated code for `FromForm` now returns
an error value indicating the error condition. The `FromFormValue`
derive now accepts a `form` attribute on variants for specifying the
exact value string to match against.
Closes#590.
Closes#670.
The directory structure has changed to better isolate crates serving
core and contrib. The new directory structure is:
contrib/
lib/ - the contrib library
core/
lib/ - the core Rocket library
codegen/ - the "compile extension" codegen library
codegen_next/ - the new proc-macro library
examples/ - unchanged
scripts/ - unchanged
site/ - unchanged
This commit also removes the following files:
appveyor.yml - AppVeyor (Rust on Windows) is far too spotty for use
rustfmt.toml - rustfmt is, unfortunately, not mature enough for use
Finally, all example Cargo crates were marked with 'publish = false'.
The 'codegen_next' crate will eventually be renamed 'codegen'. It
contains procedural macros written with the upcoming 'proc_macro' APIs,
which will eventually be stabilized. All compiler extensions in the
present 'codegen' crate will be rewritten as procedural macros and moved
to the 'codegen_next' crate.
At present, macros from 'codegen_next' are exported from the core
`rocket` crate automatically. In the future, we may wish to feature-gate
this export to allow using Rocket's core without codegen.
Resolves#16.
Sessions
--------
This commit removes the `Session` type in favor of methods on the
`Cookies` types that allow for adding, removing, and getting private
(signed and encrypted) cookies. These methods provide a superset of
the functionality of `Session` while also being a minimal addition to
the existing API. They can be used to implement the previous `Session`
type as well as other forms of session storage. The new methods are:
* Cookie::add_private(&mut self, Cookie)
* Cookie::remove_private(&mut self, Cookie)
* Cookie::get_private(&self, &str)
Resolves#20
Testing
-------
This commit removes the `rocket::testing` module. It adds the
`rocket::local` module which provides a `Client` type for local
dispatching of requests against a `Rocket` instance. This `local`
package subsumes the previous `testing` package.
Rocket Examples
---------------
The `forms`, `optional_result`, and `hello_alt_methods` examples have
been removed. The following example have been renamed:
* extended_validation -> form_validation
* hello_ranks -> ranking
* from_request -> request_guard
* hello_tls -> tls
Other Changes
-------------
This commit also includes the following smaller changes:
* Config::{development, staging, production} constructors have been
added for easier creation of default `Config` structures.
* The `Config` type is exported from the root.
* `Request` implements `Clone` and `Debug`.
* `Request::new` is no longer exported.
* A `Response::body_bytes` method was added to easily retrieve a
response's body as a `Vec<u8>`.
This is a breaking change.
This commit introduces `RawStr` to forms. In particular, after this
commit, the `&str` type no longer implements `FromFormValue`, and so it
cannot be used as a field in forms. Instad, the `&RawStr` can be used.
The `FormItems` iterator now returns an `(&RawStr, &RawStr)` pair.
This commit includes the following important API changes:
* The `form` route parameter has been removed.
* The `data` route parameter has been added.
* Forms are not handled via the `data` parameter and `Form` type.
* Removed the `data` parameter from `Request`.
* Added `FromData` conversion trate and default implementation.
* Added `DataOutcome` enum, which is the return type of `from_data`.
* 'FromData' is now used to automatically derive the `data` parameter.
* Moved `form` into `request` module.
* Removed `Failure::new` in favor of direct value construction.
This commit includes the following important package additions:
* Added a 'raw_upload' example.
* `manual_routes` example uses `Data` parameter.
* Now building and running tests with `--all-features` flag.
* All exmaples have been updated to latest API.
* Now using upstream Tera.
This commit includes the following important fixes:
* Any valid ident is now allowed in single-parameter route parameters.
* Lifetimes are now properly stripped in code generation.
* `FromForm` derive now works on empty structs.
* All From* trait methods are now named like the trait.
* All From* traits have an associated Error type.
* Document all of the `form` module.
* Add codegen tests for auto-derived forms.
* The param parsing traits now live under Request.
