Cargo Features

[dependencies]
rxrust = { version = "1.0.0-beta.9", default-features = false, features = ["futures-scheduler", "tokio-scheduler", "timer"] }
default = futures-scheduler, timer

These default features are set whenever rxrust is added without default-features = false somewhere in the dependency tree.

futures-scheduler default

Enables thread-pool of futures

tokio-scheduler = tokio
timer default = futures-time

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

futures-time not wasm32 timer
tokio tokio-scheduler?
