Cargo Features

ISO-10303 has no features set by default.

iso-10303 = { version = "0.5.0", features = ["gencode", "gengraph"] }
gencode = heck, proc-macro2, quote
gengraph = heck, petgraph

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.

heck gencode? gengraph?

Enables heck ^0.3

petgraph gengraph?
