Cargo Features

[dependencies]
serde-select = { version = "0.1.0-alpha.1", default-features = false, features = ["backend_toml", "backend_serde_json"] }
default = backend_serde_json, backend_toml

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

backend_toml default = toml
backend_serde_json default = serde_json

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 toml ^0.5
