# Schema: Polkadot SDK PRDoc Schema (prdoc) v1.0.0 # See doc at https://raw.githubusercontent.com/paritytech/polkadot-sdk/master/prdoc/schema_user.json title: XCM builder pattern automatically converts instruction parameters. doc: - audience: Runtime Dev description: | Small quality of life improvement. Previously, an XCM could be built like this: ```rust let xcm = Xcm::builder() .withdraw_asset((Parent, 100u128).into()) .buy_execution((Parent, 1u128).into()) .deposit_asset(All.into(), AccountId32 { id: [0u8; 32], network: None }.into()) .build(); ``` Now, it can be built like this: ```rust let xcm = Xcm::builder() .withdraw_asset((Parent, 100u128)) .buy_execution((Parent, 1u128)) .deposit_asset(All, [0u8; 32]) .build(); ``` crates: - name: "xcm-procedural" bump: minor - name: "staging-xcm" bump: minor
