Struct EngineCapabilities 

pub struct EngineCapabilities {
    pub renders: bool,
    pub honors_viewport: bool,
    pub measures_layout: bool,
    pub persists_auth: bool,

}

What an engine declares it can and cannot do.

Fields

renders: bool

Renders pixels (pages are visually realized; capture works).

honors_viewport: bool

Honors set_viewport requests.

measures_layout: bool

Computes layout boxes (layout works).

persists_auth: bool

Persists and restores cookies / storage (save_auth / load_auth work).

inspector_console: bool

Captures console.* and uncaught exceptions in a ring buffer (M5.7 PR1+). Surfaced via vs_inspect console.

inspector_network: bool

Captures network requests in a ring buffer (M5.7 PR1+). Surfaced via vs_inspect network.

inspector_cookie_events: bool

Captures cookie-store ADD/REMOVE events in a ring buffer (v0.1.6+). Surfaced via vs_inspect cookie-events. macOS and Linux only — Windows reports false because webview2-com has no cookie-changed observer.

name: &'static str

Short identifier reported in vs_status.

version: &'static str

Engine version string. Empty for the stub.

Implementations

impl EngineCapabilities

pub const TEST: Self

Capabilities advertised by the in-memory TestEngine (in test_support). Sealed behind the test-support Cargo feature; production builds of the daemon never see this.

Trait Implementations

impl Clone for EngineCapabilities

fn clone(&self) -> EngineCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EngineCapabilities

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

Formats the value using the given formatter.

impl PartialEq for EngineCapabilities

fn eq(&self, other: &EngineCapabilities) -> 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.
