Cargo Features

[dependencies]
mdbook-plantuml = { version = "0.8.0", default-features = false, features = ["plantuml-server", "plantuml-ssl-server"] }
default = plantuml-ssl-server

The plantuml-ssl-server feature is set by default whenever mdbook-plantuml is added without default-features = false somewhere in the dependency tree.

plantuml-server = deflate, reqwest
plantuml-ssl-server default = deflate

Enables default-tls of reqwest ^0.11.10

reqwest:

Note: this doesn't enable the 'native-tls' feature, which adds specific functionality for it.

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.
