Cargo Features

Venta has no features set by default.

[dependencies]
venta = { version = "0.9.0", features = ["metrics"] }
metrics = lazy_static, prometheus

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.

lazy_static metrics?
prometheus metrics?
