Cargo Features

Wyvern has no features set by default.

[dependencies]
wyvern = { version = "1.4.1", features = ["eidolonint"] }
eidolonint = eidolon

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.
