# Function derive_deserialize

Module: `serde::serialization`

```rust
pub comptime fn derive_deserialize(s: TypeDefinition) -> Quoted
```

Generates a `Deserialize` trait implementation for a given struct `s`.

## Arguments

- `s` - The struct type definition to generate the implementation for

## Returns

A `Quoted` block containing the generated trait implementation

## Requirements

Each struct member type must implement the `Deserialize` trait (it gets used in the generated code).

## Example

For a struct like:

```rust
struct MyStruct {
    x: AztecAddress,
    y: Field,
}
```

This generates:

```rust
impl Deserialize for MyStruct {
    let N: u32 = <AztecAddress as Deserialize>::N + <Field as Deserialize>::N;

    fn deserialize(fields: [Field; Self::N]) -> Self {
        let mut reader = Reader::new(fields);
        let result = Self::stream_deserialize(&mut reader);
        reader.finish();
        result
    }

    #[inline_always]
    fn stream_deserialize<let K: u32>(reader: &mut Reader<K>) -> Self {
        let x = <AztecAddress as Deserialize>::stream_deserialize(reader);
        let y = <Field as Deserialize>::stream_deserialize(reader);
        Self { x, y }
    }
}
```
