Struct TaskIdRegistry 

pub struct TaskIdRegistry { /* private fields */ }

Task registry for managing task metadata

Implementations

impl TaskIdRegistry

pub fn new() -> Self

Create new task registry

pub fn task_scope(&self, name: &str) -> TaskGuard

Create a task scope with automatic lifecycle management

This is the simplified API - just call this and the task is automatically completed when the guard is dropped.

Arguments

• name - Task name

Returns

A TaskGuard that automatically completes the task when dropped

Example

let registry = global_registry();

{
    let _main = registry.task_scope("main_process");
    let data = vec![1, 2, 3]; // Automatically attributed to main_process

    {
        let _worker = registry.task_scope("worker"); // Parent is automatically main_process
        let more_data = vec![4, 5, 6]; // Automatically attributed to worker
    } // worker automatically completed
} // main automatically completed

let graph = registry.export_graph();

pub fn record_allocation(&self, size: usize)

Record a memory allocation for the current task

Arguments

• size - Size of the allocation in bytes

pub fn current_task_id() -> Option<u64>

Get current task ID from thread-local cache

This is a zero-cost operation (no lock required)

pub fn clear(&self)

Clear all tasks (for testing purposes)

pub fn get_task(&self, task_id: u64) -> Option<TaskMeta>

Get task metadata by ID

Arguments

• task_id - Task ID

Returns

Task metadata if found

pub fn get_all_tasks(&self) -> Vec<TaskMeta>

Get all tasks

pub fn get_children(&self, parent_id: u64) -> Vec<u64>

Get task children

Arguments

• parent_id - Parent task ID

Returns

List of child task IDs

pub fn get_parent(&self, task_id: u64) -> Option<u64>

Get task parent

Arguments

• task_id - Task ID

Returns

Parent task ID if found

pub fn export_graph(&self) -> TaskGraph

Export task graph as JSON

Returns

TaskGraph containing all tasks and their relationships

pub fn get_stats(&self) -> TaskRegistryStats

Get task statistics

Trait Implementations

impl Default for TaskIdRegistry

fn default() -> Self
