computer

Computer #
Computer is a lightweight library for concurrent computations, which provides Flutter's compute like API.
Features #

Easy to use API
No overhead on creating & releasing isolates for each task. Workers initialized on start and ready to solve your tasks
Strictly defined number of workers

Note #
Computer.shared() is a singleton, use Computer.create() to create new instances
How to use #
Computer provides just 3 methods
turnOn() #
Before using the Computer you need to turnOn it. This will create workers and initialize them. Then you may use compute() method.
final computer = Computer.create(); //Or Computer.shared()

await computer.turnOn(
workersCount: 4, // optional, default 2
verbose: false, // optional, default false
);

compute() #
compute will execute your function inside one of the workers. Function may be async. The callback argument must be a top-level or static method of a class.
final result = await computer.compute(
fib,
param: 45, // optional
);

turnOff() #
If you don't need workers anymore, you can turnOff the Computer. It will destroy workers.
await computer.turnOff();

Errors #
ComputerError the parent error for all errors/exceptions in this package
class ComputerError implements Exception {
final String message;
}

RemoteExecutionError shows up when something goes wrong in task
class RemoteExecutionError extends ComputerError {
final Capability taskCapability;
}

CancelExecutionError shows up when turnOff is called but task is processing
class CancelExecutionError extends ComputerError {
final Capability taskCapability;
}
