Cargo Features

unicode-shaper has no features set by default.

[dependencies]
unicode-shaper = { version = "0.3.0", features = ["wasm"] }
wasm = lol_alloc

Affects unicode-shaper::processText, unicode-shaper::allocUnicodeArray, unicode-shaper::free, unicode-shaper::isRTL, unicode-shaper::isCJK

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.
