Type of change request

FEATURE

Status

DONE

Target release

0.1.0



Vision: Asynchronous programming in highly I\O application like `Iroha` should give better utilization of hardware resources. Async runtimes can give better performance and some OOB functionality for futures handling.

Functional details: Rust provides an ability (via `futures` crate) to abstract over futures executing runtime.

Environmental objectives: None

Reading of Tokio vs Async-Std articles

Important aspects that were identified: 

  • async-std has a safer layer of abstraction

  • a lot of old libraries heavily depends on tokio

  • overhead (lower is better)

  • OOB functionality (contains what we need)

  • promising future (what runtime can become standard choice in a year)
