rococo-runtime = { version = "18.0.0", default-features = false, features = ["no_std", "std", "try-runtime", "runtime-benchmarks", "metadata-hash", "fast-runtime", "runtime-metrics", "on-chain-release-build"] }

default = std

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

metadata-hash build on-chain-release-build?

Enable the metadata hash generation in the wasm builder.

Enables metadata-hash of substrate-wasm-builder

fast-runtime

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

Enables fast-runtime of rococo-runtime-constants

runtime-metrics

Enables runtime-metrics of polkadot-runtime-parachains, with-tracing of sp-io

on-chain-release-build = metadata-hash

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.
