Cargo Features

[dependencies]
async-web-client = { version = "0.5.1", default-features = false, features = ["ring", "aws-lc-rs", "websocket"] }
default = ring

The ring feature is set by default whenever async-web-client is added without default-features = false somewhere in the dependency tree.

ring default

Enables ring of futures-rustls ^0.25.1

aws-lc-rs

Enables aws-lc-rs of futures-rustls ^0.25.1

websocket = async-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.

async-ws not wasm32 websocket?
