Cargo Features

Uki has no features set by default.

[dependencies]
uki = { version = "0.3.1", features = ["alloc-jem"] }
alloc-jem = jemallocator

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.

jemallocator not msvc alloc-jem?
