Cargo Features

[dependencies]
backtrace-sys = { version = "0.1.37", default-features = false, features = ["backtrace-sys", "rustc-dep-of-std"] }

default = backtrace-sys

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

Without this feature, this crate does nothing.

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.
