Cargo Features

[dependencies]
rococo-parachain-runtime = { version = "0.17.0", default-features = false, features = ["std", "runtime-benchmarks", "on-chain-release-build"] }
default = std

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

std default = substrate-wasm-builder

Enables std of parity-scale-codec, cumulus-pallet-aura-ext, cumulus-pallet-parachain-system, cumulus-pallet-xcm, cumulus-pallet-xcmp-queue, cumulus-ping, cumulus-primitives-aura, cumulus-primitives-core, cumulus-primitives-storage-weight-reclaim, cumulus-primitives-utility, optional frame-benchmarking, frame-executive, frame-support, frame-system, frame-system-rpc-runtime-api, pallet-assets, pallet-aura, pallet-balances, pallet-message-queue, pallet-sudo, pallet-timestamp, pallet-transaction-payment, pallet-transaction-payment-rpc-runtime-api, pallet-xcm, staging-parachain-info, parachains-common, polkadot-parachain-primitives, polkadot-runtime-common, scale-info, sp-api, sp-block-builder, sp-consensus-aura, sp-core, sp-genesis-builder, sp-inherents, sp-offchain, sp-runtime, sp-session, sp-transaction-pool, sp-version, testnet-parachains-constants, staging-xcm, staging-xcm-builder, and staging-xcm-executor

Affects rococo-parachain-runtime::native_version

runtime-benchmarks

Enables runtime-benchmarks of cumulus-pallet-parachain-system, cumulus-pallet-xcmp-queue, cumulus-primitives-core, cumulus-primitives-utility, frame-benchmarking, frame-support, frame-system, pallet-assets, pallet-balances, pallet-message-queue, pallet-sudo, pallet-timestamp, pallet-xcm, parachains-common, polkadot-parachain-primitives, polkadot-runtime-common, sp-runtime, staging-xcm-builder, and staging-xcm-executor

on-chain-release-build

A feature that should be enabled when the runtime should be built for on-chain deployment. This will disable stuff that shouldn't be part of the on-chain wasm to make it smaller, like logging for example.

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.
