Cargo Features

[dependencies]
polkadot-parachain = { version = "1.0.0", default-features = false, features = ["std", "wasm-api", "runtime-benchmarks"] }

default = std

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

std default

Enables std of serde, sp-core ^22.0.0, sp-runtime ^25.0.0, and sp-std ^9.0.0

serde:

all optional crates.

and std of bounded-collections ^0.1.8, frame-support ^22.0.0, parity-scale-codec, polkadot-core-primitives ^1.0.0, and scale-info

parity-scale-codec:

note: special care is taken to avoid inclusion of sp-io externals when compiling this crate for WASM. This is critical to avoid forcing all parachain WASM into implementing various unnecessary Substrate-specific endpoints.
