Cargo Features

[dependencies]
float_duration = { version = "0.3.3", default-features = false, features = ["all", "nightly"] }
default = approx, chrono, serde, time

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

all = approx, chrono, serde, time
nightly

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.

chrono default all?
time default all?

Enables time ^0.1.37

approx default all?
