## Mandatory feature:
## This feature is required to keep the compatibility with Slint 1.2
## Newer patch version may put current functionality behind a new feature
## that would be enabled by default only if this feature was added.
## [More info in this blog post](https://slint.dev/blog/rust-adding-default-cargo-feature.html)
"compat-1-2" = []
"compat-1-0" = ["compat-1-2", "renderer-software"]

## Enable use of the Rust standard library.
std = ["i-slint-core/std"]

## Enable the translations using [gettext](https://www.gnu.org/software/gettext/gettext)
##
## the `@tr(...)` code from .slint files will be transformed into call to `dgettext`
## with the crate name as domain name
##
## translations must be enabled with the [`init_translations!`] macro
gettext = ["i-slint-core/gettext-rs"]

## This feature enables floating point arithmetic emulation using the [libm](https://crates.io/crates/libm) crate. Use this
## in MCU environments where the processor does not support floating point arithmetic.
libm = ["i-slint-core/libm"]

## If enabled, calls of `debug()` in `.slint` files use to the [`log::debug!()`] macro
## of the [log](https://crates.io/crates/log) crate instead of just `println!()`.
log = ["dep:log"]

## Implement the `serde::Serialize` and `serde::Deserialize` for some of the base types
## such as `SharedString` and `SharedVector`.
serde = ["i-slint-core/serde"]

## This feature enables the software renderer to pick up fonts from the operating system for text rendering.
software-renderer-systemfonts = ["renderer-software", "i-slint-core/software-renderer-systemfonts"]

## Slint uses internally some `thread_local` state.
##
## When the `std` feature is enabled, Slint can use [`std::thread_local!`], but when in a `#![no_std]`
## environment, we need a replacement. Using this feature, Slint will just use static variable
## disregarding Rust's Send and Sync safety
##
## **Safety** : You must ensure that there is only one single thread that call into the Slint API
unsafe-single-threaded = ["i-slint-core/unsafe-single-threaded"]

## Enable integration with operating system provided accessibility APIs
##
## Enabling this feature will try to expose the tree of UI elements to OS provided accessibility
## APIs to support screen readers and other assistive technologies.
accessibility = ["i-slint-backend-selector/accessibility"]

#! ### Backends

#! Slint needs a backend that will act as liaison between Slint and the OS.
#! By default, Slint will use the Qt backend, if Qt is installed, otherwise, it
#! will use [Winit](https://crates.io/crates/winit) with [FemtoVG](https://crates.io/crates/femtovg).
#! Both backends are compiled in. If you want to not compile one of these you need
#! to disable the default feature and re-enable one backend. It is also possible
#! to use Slint without backend if you provide the platform abstraction yourself
#! with [`platform::set_platform()`].
#!
#! If you enable the Winit backend, you need to also include a renderer.
#! `renderer-femtovg` is the only stable renderer, the other ones are experimental
#!
#! It is also possible to select the backend and renderer at runtime when several
#! are enabled, using the `SLINT_BACKEND`  environment variable.
#!  * `SLINT_BACKEND=Qt` selects the Qt backend
#!  * `SLINT_BACKEND=winit` selects the winit backend
#!  * `SLINT_BACKEND=winit-femtovg` selects the winit backend with the FemtoVG renderer
#!  * `SLINT_BACKEND=winit-skia` selects the winit backend with the skia renderer
#!  * `SLINT_BACKEND=winit-software` selects the winit backend with the software renderer
#!
#! If the selected backend is not available, the default will be used.
#!
#! Here are the cargo features controlling the backend:

## The Qt backend feature uses Qt for the windowing system integration and rendering.
## This backend also provides the `native` style.
## It requires Qt 5.15 or later to be installed. If Qt is not installed, the
## backend will not be operational
backend-qt = ["i-slint-backend-selector/i-slint-backend-qt", "std"]

## The [winit](https://crates.io/crates/winit) crate is used for the event loop and windowing system integration.
## It supports Windows, macOS, web browsers, X11 and Wayland. X11 and wayland are only available when
## compiling for Linux or other Unix-like operating systems. With this feature, both X11 and Wayland are supported.
## For a smaller build, omit this feature and select one of the other specific `backend-winit-XX` features.
backend-winit = ["i-slint-backend-selector/backend-winit", "std"]

## Simliar to `backend-winit` this enables the winit based event loop but only
## with support for the X Window System on Unix.
backend-winit-x11 = ["i-slint-backend-selector/backend-winit-x11", "std"]

## Simliar to `backend-winit` this enables the winit based event loop but only
## with support for the Wayland window system on Unix.
backend-winit-wayland = ["i-slint-backend-selector/backend-winit-wayland", "std"]

## Same as `renderer-skia`, but Skia will always use OpenGL.

## Render using the software renderer.
renderer-software = ["i-slint-backend-selector/renderer-software", "i-slint-core/software-renderer"]

## KMS with Vulkan or EGL and libinput on Linux are used to render the application in full screen mode, without any
## windowing system. Requires libseat. If you don't have libseat, select `backend-linuxkms-noseat` instead. (Experimental)
