Cargo Features

[dependencies]
iconify = { version = "0.3.1", default-features = false, features = ["tls", "cache", "offline"] }
default = cache, tls

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

tls default

Enables tls of ureq

cache default = blake3, directories
offline = blake3

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.

directories cache
blake3 cache offline?
