Cargo Features

http-encoding has no features set by default.

[dependencies]
http-encoding = { version = "0.2.0", features = ["all", "br", "gz", "de"] }
all = br, de, gz
br all? = brotli2
gz all? = flate2
de all? = flate2

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.
