Struct RendererRegistry 

pub struct RendererRegistry { /* private fields */ }

Implementations

impl RendererRegistry

pub fn new() -> Self

Creates a new RendererRegistry with default settings (max_pending=100). Use with_max_pending() to customize the limit.

pub fn with_max_pending(max_pending: usize) -> Self

Creates a new RendererRegistry with a custom max pending requests limit.

pub async fn register(&self, session: RendererSession) -> Result<RendererId>

Registers a renderer session. Returns Ok(id) on success, or Err if the name is already in use (first-wins policy). Atomic check-and-insert ensures no race conditions with concurrent registration attempts.

pub async fn unregister(&self, id: &str, connection_id: Uuid)

Unregisters a renderer session, but only if the connection_id matches. This prevents a refused or late-cleaning-up connection from unregistering a different session that took over the name. The renderer stays listed afterwards, as disconnected.

pub async fn get_info(&self, id: &str) -> Result<RendererInfo>

Connected, or disconnected since this process started.

pub async fn list_info(&self) -> Vec<RendererInfo>

Connected renderers plus ones that disconnected since this process started — check RendererInfo::is_connected to tell them apart.

pub fn graphic_in_use(&self, graphic_id: &str) -> bool

Whether any connected renderer has an instance of graphic_id — a deleted graphic’s files stay until this is false.

pub async fn send_and_await( &self, renderer_id: &str, build: impl FnOnce(Uuid) -> ServerMessage, timeout: Duration, ) -> Result<RendererMessage>

Sends a command to a renderer and waits for its correlated result. The OGraf spec requires load()/playAction()/etc HTTP responses to reflect what actually happened inside the GraphicInstance, so this is the only way commands reach a renderer — no fire-and-forget.

pub async fn resolve( &self, renderer_id: &str, request_id: Uuid, message: RendererMessage, )

Applies a renderer-confirmed result to session state (so GET renderer endpoints reflect renderer-confirmed truth, not what was merely sent) and wakes up the HTTP handler awaiting it via send_and_await, if any.

Trait Implementations

impl Default for RendererRegistry

fn default() -> Self

Returns the “default value” for a type.
