Cargo Features

[dependencies]
rustracing = { version = "0.6.0", default-features = false, features = ["stacktrace"] }
default = stacktrace

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

stacktrace default = backtrace

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.
