Cargo Features

[dependencies]
tax_ids = { version = "0.1.0", default-features = false, features = ["eu_vat", "gb_vat", "ch_vat", "no_vat"] }
default = eu_vat

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

eu_vat default = roxmltree
gb_vat
ch_vat = roxmltree
no_vat = toml

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.

roxmltree ch_vat? eu_vat

Enables roxmltree ^0.19.0
