Cargo Features

[dependencies]
tracing-tree2 = { version = "0.3.0", default-features = false, features = ["tracing-log"] }
default = tracing-log

The tracing-log feature is set by default whenever tracing-tree2 is added without default-features = false somewhere in the dependency tree.

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.
