Cargo Features

[dependencies]
deno_node_transform = { version = "0.6.0", default-features = false, features = ["tokio-loader", "serialization"] }
default = tokio-loader

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

tokio-loader default = reqwest, tokio
serialization = serde

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.

reqwest tokio-loader

Enables reqwest ^0.11
