Cargo Features

epub-builder = { version = "0.7.4", default-features = false, features = ["zip-command", "zip-library"] }
default = zip-command, zip-library

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

zip-command default = tempfile
zip-library default = libzip

Enable libzip directly to avoid non-reproducible timestamps in the zip file.

Enables time of zip

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.

tempfile zip-command
libzip zip-library

Enables zip
