Cargo Features

aya-metrics has no features set by default.

[dependencies]
aya-metrics = { version = "0.2.0", features = ["mocks"] }
mocks = aya-metrics-mocks

Make mocks available as a feature

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.
