Cargo Features

texel = { version = "0.2.5", default-features = false, features = ["ion", "crossterm"] }
default = crossterm

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

ion = termion

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.
