Async Job System

#import "std/async"

Async module provides high-level interface for thread manipulation. In general, it's suitable for longer running parallel tasks expecting some input context and results returned back to the caller.

std.Async

Async :: fn (TWorkerContext: type, TResult: type) type

Asynchronous task context holder holding internally created thread instance, input and output data of the worker function. Instance of this type is supposed to be initialized exclusively in async function call and its content is internal.

std.async

async :: fn (ctx: *?TAsync, worker_context: , worker: *fn (ctx: ) ) 

Setup the async ctx context structure and starts internally a new thread executing the worker function. The worker runtime context must be specified as worker_context. The execution (worker return) result value is not returned immediately since call to this function is not blocking. Use async_wait to get the cached result value back.

std.async_wait

async_wait :: fn (ctx: *?TAsync)  #inline

Wait for the async job, executed by async call, to finish. This function blocks until the underlying job's thread exits. The result value is returned on success.
