Struct PreviewFrame 

pub struct PreviewFrame { /* private fields */ }

What the preview frame’s document needs, read once at start: the inline runtime, its SHA-256 and the application’s origin (see the module docs).

Implementations

impl PreviewFrame

pub fn load<A: Embed>( manifest: &AssetManifest, app_origin: &str, ) -> Result<Self, FrameError>

Read the runtime the manifest names under FRAME_RUNTIME_ASSET from the application’s embedded files A, hash it for script-src, and check app_origin, the origin of the pages that frame it (https://studio.example).

Errors

FRAME-101 to FRAME-104 (see the module docs); refuse to start on any of them.
