Cargo Features

[dependencies]
markdown-it = { version = "0.6.0", default-features = false, features = ["linkify", "syntect"] }
default = linkify, syntect

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

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.

linkify default

Affects extra::linkify
