The Servo Browser Engine
Bumps [rayon-core](https://github.com/rayon-rs/rayon) from 1.12.1 to 1.13.0. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/rayon-rs/rayon/blob/main/RELEASES.md">rayon-core's changelog</a>.</em></p> <blockquote> <h1>Release rayon 1.11.0 / rayon-core 1.13.0 (2025-08-12)</h1> <ul> <li>The minimum supported <code>rustc</code> is now 1.80.</li> <li><code>iter::repeatn</code> has been renamed to <code>iter::repeat_n</code> to match the name stabilized in the standard library. The old name still exists as a deprecated function for compatibility.</li> <li>Fixed a bug in <code>in_place_scope</code> when the default global registry uses the current thread, like on WebAssembly without threading support.</li> <li><code>binary_heap::Iter</code> no longer requires a temporary allocation.</li> <li>Relaxed trait bounds on many of the public structs.</li> <li>Implemented <code>IntoParallelIterator for Box<[T]></code> and its references.</li> <li>Implemented <code>FromParallelIterator<_> for Box<str></code> via <code>String</code>.</li> </ul> <h1>Release rayon 1.10.0 (2024-03-23)</h1> <ul> <li>The new methods <code>ParallelSlice::par_chunk_by</code> and <code>ParallelSliceMut::par_chunk_by_mut</code> work like the slice methods <code>chunk_by</code> and <code>chunk_by_mut</code> added in Rust 1.77.</li> </ul> <h1>Release rayon 1.9.0 (2024-02-27)</h1> <ul> <li>The new methods <code>IndexedParallelIterator::by_exponential_blocks</code> and <code>by_uniform_blocks</code> allow processing items in smaller groups at a time.</li> <li>The new <code>iter::walk_tree</code>, <code>walk_tree_prefix</code>, and <code>walk_tree_postfix</code> functions enable custom parallel iteration over tree-like structures.</li> <li>The new method <code>ParallelIterator::collect_vec_list</code> returns items as a linked list of vectors, which is an efficient mode of parallel collection used by many of the internal implementations of <code>collect</code>.</li> <li>The new methods <code>ParallelSliceMut::par_split_inclusive_mut</code>, <code>ParallelSlice::par_split_inclusive</code>, and <code>ParallelString::par_split_inclusive</code> all work like a normal split but keeping the separator as part of the left slice.</li> <li>The new <code>ParallelString::par_split_ascii_whitespace</code> splits only on ASCII whitespace, which is faster than including Unicode multi-byte whitespace.</li> <li><code>OsString</code> now implements <code>FromParallelIterator<_></code> and <code>ParallelExtend<_></code> for a few item types similar to the standard <code>FromIterator</code> and <code>Extend</code>.</li> <li>The internal <code>Pattern</code> trait for string methods is now implemented for <code>[char; N]</code> and <code>&[char; N]</code>, matching any of the given characters.</li> </ul> </blockquote> </details> <details> <summary>Commits</summary> <ul> <li><a href=" |

The Servo Parallel Browser Engine Project
Servo is a prototype web browser engine written in the Rust language. It is currently developed on 64-bit macOS, 64-bit Linux, 64-bit Windows, 64-bit OpenHarmony, and Android.
Servo welcomes contribution from everyone. Check out:
- The Servo Book for documentation
- servo.org for news and guides
Coordination of Servo development happens:
- Here in the Github Issues
- On the Servo Zulip
- In video calls advertised in the Servo Project repo.
Getting started
For more detailed build instructions, see the Servo book under Setting up your environment, Building Servo, Building for Android and Building for OpenHarmony.
macOS
- Download and install Xcode and
brew
. - Install
uv
:curl -LsSf https://astral.sh/uv/install.sh | sh
- Install
rustup
:curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
- Restart your shell to make sure
cargo
is available - Install the other dependencies:
./mach bootstrap
- Build servoshell:
./mach build
Linux
- Install
curl
:- Arch:
sudo pacman -S --needed curl
- Debian, Ubuntu:
sudo apt install curl
- Fedora:
sudo dnf install curl
- Gentoo:
sudo emerge net-misc/curl
- Arch:
- Install
uv
:curl -LsSf https://astral.sh/uv/install.sh | sh
- Install
rustup
:curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
- Restart your shell to make sure
cargo
is available - Install the other dependencies:
./mach bootstrap
- Build servoshell:
./mach build
Windows
- Download
uv
,choco
, andrustup
- Be sure to select Quick install via the Visual Studio Community installer
- In the Visual Studio Installer, ensure the following components are installed:
- Windows 10/11 SDK (anything >= 10.0.19041.0) (
Microsoft.VisualStudio.Component.Windows{10, 11}SDK.{>=19041}
) - MSVC v143 - VS 2022 C++ x64/x86 build tools (Latest) (
Microsoft.VisualStudio.Component.VC.Tools.x86.x64
) - C++ ATL for latest v143 build tools (x86 & x64) (
Microsoft.VisualStudio.Component.VC.ATL
) - C++ MFC for latest v143 build tools (x86 & x64) (
Microsoft.VisualStudio.Component.VC.ATLMFC
)
- Windows 10/11 SDK (anything >= 10.0.19041.0) (
- Restart your shell to make sure
cargo
is available - Install the other dependencies:
.\mach bootstrap
- Build servoshell:
.\mach build
Android
- Ensure that the following environment variables are set:
ANDROID_SDK_ROOT
ANDROID_NDK_ROOT
:$ANDROID_SDK_ROOT/ndk/26.2.11394342/
ANDROID_SDK_ROOT
can be any directory (such as~/android-sdk
). All of the Android build dependencies will be installed there.
- Install the latest version of the Android command-line
tools to
$ANDROID_SDK_ROOT/cmdline-tools/latest
. - Run the following command to install the necessary components:
sudo $ANDROID_SDK_ROOT/cmdline-tools/latest/bin/sdkmanager --install \ "build-tools;34.0.0" \ "emulator" \ "ndk;26.2.11394342" \ "platform-tools" \ "platforms;android-33" \ "system-images;android-33;google_apis;x86_64"
- Follow the instructions above for the platform you are building on
OpenHarmony
- Follow the instructions above for the platform you are building on to prepare the environment.
- Depending on the target distribution (e.g.
HarmonyOS NEXT
vs pureOpenHarmony
) the build configuration will differ slightly. - Ensure that the following environment variables are set
DEVECO_SDK_HOME
(Required when targetingHarmonyOS NEXT
)OHOS_BASE_SDK_HOME
(Required when targetingOpenHarmony
)OHOS_SDK_NATIVE
(e.g.${DEVECO_SDK_HOME}/default/openharmony/native
or${OHOS_BASE_SDK_HOME}/${API_VERSION}/native
)SERVO_OHOS_SIGNING_CONFIG
: Path to json file containing a valid signing configuration for the demo app.
- Review the detailed instructions at Building for OpenHarmony.
- The target distribution can be modified by passing
--flavor=<default|harmonyos>
to `mach <build|package|install>.
