class Fiber::ExecutionContext::Parallel::Scheduler

Overview

Individual scheduler for the parallel execution context.

The execution context itself doesn't run the fibers. The fibers actually run in the schedulers. Each scheduler in the context increases the parallelism by one. For example a parallel context with 8 schedulers means that a maximum of 8 fibers may run at the same time in different system threads.

Included Modules

  • Fiber::ExecutionContext::Scheduler

Defined in:

fiber/execution_context/parallel/scheduler.cr

Instance Method Summary

  • #inspect(io : IO) : Nil

    Appends a String representation of this object which includes its class name, its object address and the values of all instance variables.

  • #name : String
  • #status : String

    Returns the current status of the scheduler.

  • #to_s(io : IO) : Nil

    Appends a short String representation of this object which includes its class name and its object address.

Instance Method Detail

def inspect(io : IO) : NilSource

Description copied from class Reference

Appends a String representation of this object which includes its class name, its object address and the values of all instance variables.

class Person
  def initialize(@name : String, @age : Int32)
  end
end

Person.new("John", 32).inspect # => #<Person:0x10fd31f20 @name="John", @age=32>

def name : StringSource

def status : StringSource

Description copied from module Fiber::ExecutionContext::Scheduler

Returns the current status of the scheduler. For example "running", "event-loop" or "parked".

def to_s(io : IO) : NilSource

Description copied from class Reference

Appends a short String representation of this object which includes its class name and its object address.

class Person
  def initialize(@name : String, @age : Int32)
  end
end

Person.new("John", 32).to_s # => #<Person:0x10a199f20>
