Cargo Features

[dependencies]
khash = { version = "2.0.4", default-features = false, features = ["ffi", "crc"] }
default = crc, ffi

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

ffi default = libc, malloc-array

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.

malloc-array ffi
libc ffi
crc default

Enables crc ^1.8
