Cargo Features

[dependencies]
theory = { version = "0.1.0", default-features = false, features = ["deflate", "lz4"] }
default = deflate, lz4

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

deflate default = flate2
lz4 default = lz4_flex

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.
