Enhanced Task trait with improved type safety and async characteristics

Required Methods

fn execute<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = TaskResult> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Execute the task with comprehensive error handling

fn name(&self) -> &str

Task identifier for registration and execution

Provided Methods

fn max_retries(&self) -> u32

Maximum retry attempts (default: 3)

fn timeout_seconds(&self) -> u64

Task timeout in seconds (default: 300s/5min)

fn priority(&self) -> TaskPriority

Task priority level (default: Normal)

fn resource_requirements(&self) -> TaskResourceRequirements

Estimate task resource requirements for better scheduling

fn retry_delay_strategy(&self) -> RetryStrategy

Custom retry delay strategy

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
