Cargo Features

sea-streamer-examples = { version = "0.5.0", default-features = false, features = ["runtime-tokio", "runtime-async-std"] }
default = runtime-tokio

The runtime-tokio feature is set by default whenever sea-streamer-examples is added without default-features = false somewhere in the dependency tree.

runtime-tokio default = tokio

Enables runtime-tokio of sea-streamer

runtime-async-std = async-std

Enables runtime-async-std of sea-streamer

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.

async-std runtime-async-std?
tokio runtime-tokio
