Cargo Features

[dependencies]
clickhouse-rs = { version = "1.1.0-alpha.1", default-features = false, features = ["tls", "async_std", "tokio_io"] }
default = tokio_io

The tokio_io feature is set by default whenever clickhouse-rs is added without default-features = false somewhere in the dependency tree.

tls = native-tls, tokio-native-tls

Affects options::Certificate

async_std = async-std
tokio_io default = tokio

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 async_std?
native-tls tls?
tokio tokio_io
tokio-native-tls tls?
