Cargo Features

[dependencies]
abs_art = { version = "0.1.0", default-features = false, features = ["runtime-async-std", "runtime-tokio", "runtime-smol"] }
default = runtime-tokio

The runtime-tokio feature is set by default whenever abs_art is added without default-features = false somewhere in the dependency tree.

runtime-async-std = async-std
runtime-tokio default = tokio
runtime-smol = async-executor, scoped-tls, smol

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.

Enables async-std 1.12.*

smol runtime-smol?
tokio runtime-tokio
scoped-tls runtime-smol?
