* Allowlist types generated by bindgen
Tidied up build script as well, layout tests are no longer generated
unless `EXT_PHP_RS_TEST` env variable is set. Much quicker build times
and smaller output size.
* Fix build
* Override Rust toolchain when running CI
* Start work on returning new objects
Change `IntoZval` to consume `self`
* Add conversion from vector reference to PHP hashtable through clones
* `set_binary` now only takes `Vec`
Used to take `AsRef<[T]>` to allow users to pass arrays, however, this
causes the data to be cloned even if the user passes a `Vec`.
* Rename `as_zval` to `into_zval` to match Rust conventions
* Started work on closures
* Finish implementation of closures
* Document closures, add to prelude, feature gate
* Fixed closure example
* Started work on guide, added types
* Rewrite argument parser to allow referencs
Primarly so that `&str` is a valid parameter type.
* Remove generic `Into<String>` conversion to exception
* Worked on guide, added macros
* Build guide when building docs
* Allow manual trigger of docs build
* `cargo fmt`
* Added support for PHP ZTS
* Added GitHub action for ZTS
Runs seperate from the other tests, as the setup-php action does not
support ZTS, therefore we run the tests in a Docker container.
* Source Rust env file before building
* No `source` command on docker
* Another attempt at fixing Rust in Docker
