Cargo Features

[dependencies]
olio = { version = "1.4.0", default-features = false, features = ["mmap"] }
default = mmap

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

mmap default = memmap

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.
