Cargo Features

[dependencies]
btreemultimap = { version = "0.1.1", default-features = false, features = ["serde_impl"] }
default = serde_impl

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

serde_impl default = serde

Affects btreemultimap::serde

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.
