Cargo Features

[dependencies]
polkadot-runtime-common = { version = "17.0.0", default-features = false, features = ["no_std", "std", "try-runtime", "runtime-benchmarks"] }
default = std

The std feature is set by default whenever polkadot-runtime-common is added without default-features = false somewhere in the dependency tree.

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.

pallet-asset-rate runtime-benchmarks? try-runtime?
frame-benchmarking runtime-benchmarks?
pallet-babe runtime-benchmarks?
xcm-executor runtime-benchmarks? std
