Cargo Features

[dependencies]
ftx = { version = "0.5.0", default-features = false, features = ["ws"] }
default = ws

The ws feature is set by default whenever ftx is added without default-features = false somewhere in the dependency tree.

ws default = futures, tokio, tokio-tungstenite

Affects ftx::ws

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 ws
tokio ws
tokio-tungstenite ws

Enables tokio-tungstenite ^0.14.0
