Cargo Features

[dependencies]
splines = { version = "4.3.1", default-features = false, features = ["std", "impl-cgmath", "impl-glam", "impl-nalgebra", "serialization"] }
default = std

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

std default
impl-cgmath = cgmath
impl-glam = glam
impl-nalgebra = nalgebra
serialization = serde

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.

cgmath impl-cgmath?
glam impl-glam?

Enables glam >=0.10, <0.25
