Struct SchedulerBuilder 

pub struct SchedulerBuilder {
    Count: usize,
    Configuration: HashMap<String, Concurrency>,
}

A fluent builder for creating a Scheduler instance.

This pattern provides a clear and readable API for configuring the scheduler before it is constructed. It is the primary entry point for using the Echo library.

Fields

Count: usize

The number of worker threads to be spawned in the scheduler’s pool.

Configuration: HashMap<String, Concurrency>

Configuration for named queues with concurrency limits (for future use).

Implementations

impl SchedulerBuilder

pub fn Create() -> Self

Creates a new SchedulerBuilder with default settings.

By default, the worker count is set to the number of logical CPUs on the system, with a minimum of two workers to ensure work-stealing is viable.

pub fn WithWorkerCount(self, Count: usize) -> Self

Sets the total number of worker threads for the scheduler pool.

If Count is 0, it defaults to the number of logical CPUs.

pub fn WithQueue(self, Name: &str, Limit: Concurrency) -> Self

Configures a named queue with a specific concurrency limit (for future use).

pub fn Build(self) -> Scheduler

Builds and starts the Scheduler with the specified configuration.

This method consumes the builder and returns a new, running Scheduler.

Trait Implementations

impl Default for SchedulerBuilder

fn default() -> Self

Provides a default SchedulerBuilder instance.
