Cargo Features

[dependencies]
kdl = { version = "6.2.2", default-features = false, features = ["span", "v1-fallback", "v1"] }
default = span

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

span default
v1-fallback = v1
v1 v1-fallback? = kdlv1

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.

kdlv1 v1?

Enables kdl ^4.7.0
