Struct Runtime 

pub struct Runtime { /* private fields */ }

An owned application driven one event/tick at a time. Browser hosts and automation use the same passes, input handling and software renderer as native windows.

Implementations

impl Runtime

pub fn set_agent_enabled(&mut self, enabled: bool)

Explicitly opt into the same control dispatcher used by native JSON/MCP sessions.

pub fn control( &mut self, session: &mut RpcSession, line: &[u8], ) -> Option<String>

Handle one control request without IO. The caller owns one session per connection.

impl Runtime

pub fn new( desc: &AppDesc, app: impl App + 'static, style: &'static dyn Style, ) -> Result<Self, i32>

Initialize a headless surface with the normal command-line/theme configuration. Err(2) means application initialization or framebuffer allocation failed.

pub fn step(&mut self, now_ms: u32, events: &[Event]) -> bool

Apply input edges and due timers, then render if required. False means closed. Time is milliseconds since initialization; it must advance monotonically.

pub fn frame(&self) -> &Surface

Current framebuffer for presentation or screenshot encoding.

pub fn ui(&self) -> &Ui

Read the runtime context, including dimensions and semantic widgets.

pub fn command(&mut self, id: u32, arg: u32) -> bool

Deliver a registered numeric command through the normal application callback.

pub fn finish(&mut self)

Close exactly once and deliver the existing application exit callback.

Trait Implementations

impl Drop for Runtime

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
