Struct Loop 

pub struct Loop { /* private fields */ }

Represents a single alarm event processing loop.

One instance is created per each alarm-capable low-level device. The Loop is responsible for managing the lifecycle of wake alarms, including their creation, scheduling, and cancellation. It interacts with the underlying hardware timer through a TimerOps trait object.

Implementations

impl Loop

pub fn new( scope: ScopeHandle, device_proxy: DeviceProxy, inspect: Node, utc_clock: UtcClock, ) -> Self

Creates a new instance of Loop.

This function initializes a new Loop with a connection to a low-level hardware timer device. It spawns two background tasks: one for the main timer event loop and another for monitoring UTC clock changes.

Args

• scope: The fasync::ScopeHandle to spawn background tasks in.
• device_proxy: A ffhh::DeviceProxy for communicating with the hardware timer.
• inspect: A finspect::Node for recording diagnostics.
• utc_clock: A fxr::UtcClock for tracking UTC time.

Returns

A new instance of Loop.

pub fn new_emulated( scope: ScopeHandle, inspect: Node, utc_clock: UtcClock, ) -> Self

Creates a new instance of Loop with emulated wake alarms.

This function is similar to new, but it uses an emulated timer instead of a real hardware timer. This is useful for testing environments where a hardware timer may not be available.

Args

• scope: The fasync::ScopeHandle to spawn background tasks in.
• inspect: A finspect::Node for recording diagnostics.
• utc_clock: A fxr::UtcClock for tracking UTC time.

Returns

A new instance of Loop with an emulated timer.
