Crate futures_scopes

An extension to futures-rs that offers scopes. Scopes can be used to spawn non-static futures that can reference variables on the stack that were created before the scope was created.

There are currently two different Scope types:

• For spawning local non-send/sync futures, use LocalScope.
• For spawning futures on multiple, underlying spawns, use RelayScope.

Features

The following features are available on the crate:

• local: Enables LocalScope.
• relay: Enables RelayScope.

By default both features are enabled. To only use one of the features, disable the default features and enable the feature you want to use. For example:

[dependencies]
futures-scopes = {version = "...", default-features = false, features = ["local"]}

Modules
