Expand description

The script crate contains all matters DOM.


pub use script_runtime::JSEngineSetup;


A timeline module, used to specify an AnimationTimeline which determines the time used for synchronizing animations in the script thread.
animations 🔒
The set of animations for a document.
body 🔒
devtools 🔒
Tracking of pending loads in a document.
dom 🔒
The implementation of the DOM.
euclidext 🔒
init 🔒
A module with everything layout can use from script.
Infrastructure to initiate network requests for images needed by the layout thread. The script thread needs to be responsible for them because there’s no guarantee that the responsible nodes will still exist in the future if the layout thread holds on to them during asynchronous operations.
mem 🔒
Routines for handling measuring the memory usage of arbitrary DOM nodes.
microtask 🔒
Implementation of microtasks and microtask queues. It is up to implementations of event loops to store a queue and perform checkpoints at appropriate times, as well as enqueue microtasks as required.
realms 🔒
The script module mod contains common traits and structs related to type=module for script thread or worker threads.
The script runtime contains common traits and structs commonly used by the script thread, the dom, and the worker threads.
The script thread is the thread that owns the DOM in memory, runs JavaScript, and spawns parsing and layout threads. It’s in charge of processing events for all same-origin pages in a frame tree, and manages the entire lifetime of pages in the frame tree from initial request to teardown.
The service worker manager persists the descriptor of any registered service workers. It also stores an active workers map, which holds descriptors of running service workers. If an active service worker timeouts, then it removes the descriptor entry from its active_workers map
task 🔒
Machinery for tasks.
task_queue 🔒
Machinery for task-queue.
Common handling of keyboard input and state management for text input controls
timers 🔒
