The XCM builder pattern lets you build xcms like so:
```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();
```
All the `.into()` become quite annoying to have to write.
I accepted `impl Into<T>` instead of `T` in the generated methods from
the macro.
Now the previous example can be simplified as follows:
```rust
let xcm = Xcm::builder()
.withdraw_asset((Parent, 100u128))
.buy_execution((Parent, 1u128))
.deposit_asset(All, [0u8; 32])
.build();
```

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();
|
|
```
