Cargo Features

VecMap has no features set by default.

[dependencies]
vec_map = { version = "0.8.2", features = ["eders"] }
eders = serde

This feature is kept for backwards compatibility. Use feature "serde" instead.

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.
