Cargo Features

websocket = { version = "0.27.0", default-features = false, features = ["sync", "sync-ssl", "async", "async-ssl", "nightly"] }
default = async, async-ssl, sync, sync-ssl

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

sync default sync-ssl

Enables sync of websocket-base

Affects client::sync, websocket::receiver, websocket::sender, websocket::sync, server::sync, upgrade::sync, server::WsServer, upgrade::validate

sync-ssl default = native-tls, sync

Enables sync-ssl of websocket-base

async default async-ssl = bytes, futures, tokio-codec, tokio-io, tokio-reactor, tokio-tcp

Enables async of websocket-base

Affects client::r#async, websocket::codec, websocket::r#async, result::r#async, server::r#async, upgrade::r#async, server::WsServer, upgrade::validate

async-ssl default = async, native-tls, tokio-tls

Enables async-ssl of websocket-base
