Struct DMSCResourceScheduler 

pub struct DMSCResourceScheduler { /* private fields */ }

Resource scheduling algorithm using performance history and policies

This scheduler uses device performance history, current load, and custom policies to intelligently allocate resources to the most suitable devices.

Implementations

impl DMSCResourceScheduler

pub fn new() -> Self

Create a new resource scheduler with default settings.

This method initializes the scheduler with empty performance history, device loads, and scheduling policies.

Returns

A new DMSCResourceScheduler instance with default settings.

pub fn schedule_resource( &mut self, request: &ResourceRequest, available_devices: &[DMSCDevice], ) -> Option<String>

Schedule a resource request to the most suitable device based on capabilities, load, and policies.

This method evaluates available devices against the resource request requirements, calculates a score for each suitable device, and returns the ID of the best device.

Parameters

• request: Resource request with requirements and priority
• available_devices: List of available devices to consider for scheduling

Returns

The ID of the most suitable device for the request, or None if no suitable device is found.

pub fn record_performance( &mut self, device_id: &str, latency_ms: f64, throughput: f64, error_rate: f64, utilization: f64, )

Record device performance after task completion.

This method records performance metrics for a device, including latency, throughput, error rate, and utilization. These records are used for future scheduling decisions.

Parameters

• device_id: ID of the device whose performance is being recorded
• latency_ms: Latency in milliseconds
• throughput: Throughput in operations per second
• error_rate: Error rate as a fraction (0.0 to 1.0)
• utilization: Resource utilization as a fraction (0.0 to 1.0)

pub fn update_device_load(&mut self, device_id: &str, load: f64)

Update the current load of a device.

This method updates the load of a device, clamping the value between 0.0 and 1.0. The load is used in scheduling decisions to avoid overloading devices.

Parameters

• device_id: ID of the device whose load is being updated
• load: New load value (0.0 to 1.0)

pub fn add_policy(&mut self, policy: SchedulingPolicy)

Add a scheduling policy to the scheduler.

This method adds a scheduling policy to the scheduler and sorts the policies by priority (highest first) to ensure they are evaluated in the correct order.

Parameters

• policy: Scheduling policy to add
