Cargo Features

wasm-contract = { version = "0.0.0", default-features = false, features = ["validation"] }
default = validation

The validation feature is set by default whenever wasm-contract is added without default-features = false somewhere in the dependency tree.

validation default = wasmparser

Affects wasm-contract::validate

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.
