Cargo Features

[dependencies]
myval = { version = "0.1.22", default-features = false, features = ["full", "json", "postgres", "arrow2", "arrow2_ih"] }
default full? = arrow2

The arrow2 feature is set by default whenever myval is added without default-features = false somewhere in the dependency tree.

full = default, json, polars, postgres
json full? = serde, serde_json

Affects convert::json…

postgres full? = async-stream, futures, serde, serde_json, sqlx

Affects db::postgres…
