Cargo Features

genotype_path has no features set by default.

[dependencies]
genotype_path = { version = "0.12.0", features = ["project", "parser"] }
project = parser
parser project? = genotype_parser

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.
