Expand description

The script crate contains all matters DOM.

Re-exports§

Modules§

  • A timeline module, used to specify an AnimationTimeline which determines the time used for synchronizing animations in the script thread.
  • animations πŸ”’
    The set of animations for a document.
  • body πŸ”’
  • canvas_state πŸ”’
  • devtools πŸ”’
  • Tracking of pending loads in a document.
  • dom πŸ”’
    The implementation of the DOM.
  • image_listener πŸ”’
  • init πŸ”’
  • A safe wrapper for DOM nodes that prevents layout from mutating the DOM, from letting DOM nodes escape, and from generally doing anything that it isn’t supposed to. This is accomplished via a simple whitelist of allowed operations, along with some lifetime magic to prevent nodes from escaping.
  • layout_image πŸ”’
    Infrastructure to initiate network requests for images needed by layout. 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 layout holds on to them during asynchronous operations.
  • links πŸ”’
    Defines shared hyperlink behaviour for <link>, <a>, <area> and <form> elements.
  • mem πŸ”’
    Routines for handling measuring the memory usage of arbitrary DOM nodes.
  • microtask πŸ”’
    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.
  • network_listener πŸ”’
  • realms πŸ”’
  • script_module πŸ”’
    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 triggers layout. 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
  • stylesheet_set πŸ”’
  • task πŸ”’
    Machinery for tasks.
  • task_manager πŸ”’
  • task_queue πŸ”’
    Machinery for task-queue.
  • task_source πŸ”’
  • Common handling of keyboard input and state management for text input controls
  • timers πŸ”’

Macros§

Structs§

  • A struct to store a reference to the reflector of a DOM object.

Traits§

  • A trait to allow tracing only DOM sub-objects.
  • A trait to provide access to the Reflector for a DOM object.
  • A trait to allow tracing (only) DOM objects. Types that can be traced.
  • A trait to initialize the Reflector for a DOM object.
