Enum DOMWorldKind

pub enum DOMWorldKind {
    Main,
    Secondary,
}

There are two different kinds of worlds tracked for each Frame, that represent a context for JavaScript execution. A Page might have many execution contexts

• each iframe has a “default” execution context that is always created after the frame is attached to DOM. Extension’s content scripts create additional execution contexts.

Besides pages, execution contexts can be found in Web Workers.

Variants

Main

The main world of a frame that represents the default execution context of a frame and is also created.

Secondary

Each frame gets its own isolated world with universal access

Trait Implementations

impl Clone for DOMWorldKind

fn clone(&self) -> DOMWorldKind

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DOMWorldKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DOMWorldKind

fn default() -> DOMWorldKind

Returns the “default value” for a type.

impl PartialEq for DOMWorldKind

fn eq(&self, other: &DOMWorldKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
