Feature flags of polkadot-service crate // Lib.rs

Cargo Features

[dependencies]
polkadot-service = { version = "19.0.0", default-features = false, features = ["db", "full-node", "westend-native", "rococo-native", "metadata-hash", "try-runtime", "fast-runtime", "malus", "runtime-metrics", "runtime-benchmarks"] }

default = db, full-node

These default features are set whenever polkadot-service is added without default-features = false somewhere in the dependency tree.

db default

Enables rocksdb of sc-service

sc-service:
The RocksDB feature activates the RocksDB database backend. If it is not activated, and you pass a path to a database, an error will be produced at runtime.

Affects polkadot-service::overseer, polkadot-service::workers, polkadot-service::FullBackend, polkadot-service::FullClient, polkadot-service::open_database, polkadot-service::NewFullParams, polkadot-service::NewFull, polkadot-service::IsParachainNode, polkadot-service::new_full, polkadot-service::new_chain_ops, polkadot-service::build_full, polkadot-service::revert_backend, parachains_db::open_creating_rocksdb, parachains_db::open_creating_paritydb…

westend-native = frame-metadata-hash-extension, westend-runtime, westend-runtime-constants

Configure the native runtimes to use.

Affects chain_spec::WestendChainSpec, chain_spec::westend_staging_testnet_config, chain_spec::westend_development_config, chain_spec::westend_local_testnet_config…

rococo-native = frame-metadata-hash-extension, rococo-runtime, rococo-runtime-constants

Affects chain_spec::RococoChainSpec, chain_spec::rococo_staging_testnet_config, chain_spec::versi_staging_testnet_config, chain_spec::rococo_development_config, chain_spec::versi_development_config, chain_spec::rococo_local_testnet_config, chain_spec::versi_local_testnet_config…

metadata-hash

Generate the metadata hash needed for CheckMetadataHash in the test runtimes.

Enables metadata-hash of optional rococo-runtime and optional westend-runtime

try-runtime

Enables try-runtime of frame-system, pallet-transaction-payment, polkadot-runtime-parachains, optional rococo-runtime, sp-runtime, and optional westend-runtime

fast-runtime

Enables fast-runtime of optional rococo-runtime and optional westend-runtime

rococo-runtime:
Set timing constants (e.g. session period) to faster versions to speed up testing.

malus = full-node

runtime-metrics

Enables runtime-metrics of polkadot-runtime-parachains, optional rococo-runtime, and optional westend-runtime

runtime-benchmarks

Enables runtime-benchmarks of frame-benchmarking, frame-benchmarking-cli, frame-system, polkadot-primitives, polkadot-runtime-parachains, optional rococo-runtime, sc-service, sp-runtime, optional westend-runtime, and xcm-runtime-apis

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.
