Cargo Features

resterror-derive has no features set by default.

[dependencies]
resterror-derive = { version = "0.1.3", features = ["actix", "po", "verbose", "json"] }
actix = actix-web
po = poreader
verbose
json = serde, serde_json

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.

actix-web actix?
poreader po?
serde json?
serde_json json?
