Struct HostRouter 

pub struct HostRouter { /* private fields */ }

One router per connection: the surfaces it created, the packages installed, the extension catalogs negotiated.

Implementations

impl HostRouter

pub fn new<S: AsRef<str>>(extension_ids: &[S]) -> Self

extension_ids = the extension catalog ids the host registered.

pub fn with_extensions<S: AsRef<str>>( extension_ids: &[S], extensions: Option<Vec<AvailableExtension>>, ) -> Self

Self::new with the registered extensions’ versions and components (the TS HostRouterOptions.extensions).

pub fn supported_catalog_ids(&self) -> Vec<String>

pub fn register_extension(&mut self, id: &str)

pub fn register_extension_with( &mut self, id: &str, available: Option<AvailableExtension>, )

VAPP-161: with its version and components (None = {id}), kept when the router checks extensions at all.

pub fn install_package(&mut self, pkg: &Value) -> Vec<PackageIssue>

Install a declarative package: its templates become applyTemplate targets. Returns the validation issues (installed only when none).

pub fn package(&self, id: &str) -> Option<&Value>

pub fn surface(&self, id: &str) -> Option<&SurfaceInfo>

pub fn surface_ids(&self) -> Vec<String>

In creation order.

pub fn package_id_of(&self, surface_id: &str) -> Option<String>

The package whose template created the surface.

pub fn route(&mut self, message: &Value) -> Vec<Value>

One server message → the ops to perform, in order. Never fails. VAPP-103: a message past maxMessageBytes (as UTF-8 JSON) is refused: INVALID_MESSAGE.
