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".
