Cargo Features

[dependencies]
ironcalc_base = { version = "0.3.0", default-features = false, features = ["use_regex_full", "use_regex_lite"] }
default = use_regex_full

The use_regex_full feature is set by default whenever ironcalc_base is added without default-features = false somewhere in the dependency tree.

use_regex_full default = regex
use_regex_lite = regex-lite

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.
