Cargo Features

[dependencies]
flex-dns = { version = "1.0.1", default-features = false, features = ["vec", "arrayvec", "heapless"] }

default = arrayvec, heapless

These default features are set whenever flex-dns is added without default-features = false somewhere in the dependency tree.

vec

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.
