Cargo Features

[dependencies]
file_wrap = { version = "0.2.0", default-features = false, features = ["use_failure"] }
default = use_failure

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

use_failure default = failure, failure_derive

Affects file_wrap::FromFile.from_file, file_wrap::FromFile.deserialize, file_wrap::ToFile.to_file, file_wrap::ToFile.serialize, file_wrap::Failure

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.
