# Struct MembershipWitness

Module: `noir_aztec::protocol::merkle_tree::membership`

```rust
pub struct MembershipWitness<let N: u32> {
    pub leaf_index: Field,
    pub sibling_path: [Field; N],
}
```

## Fields

```rust
leaf_index: Field
```

```rust
sibling_path: [Field; N]
```

## Trait implementations

```rust
impl<let N: u32> Deserialize for MembershipWitness<N>
```

```rust
pub fn deserialize(fields: [Field; N + 1]) -> Self
```

```rust
pub fn stream_deserialize<let K: u32>(reader: &mut Reader<K>) -> Self
```

```rust
impl<let N: u32> Empty for MembershipWitness<N>
```

```rust
pub fn empty() -> Self
```

```rust
pub fn is_empty(self: Self) -> bool
where
    Self: Eq
```

```rust
pub fn assert_empty<let S: u32>(self: Self, msg: str<S>)
where
    Self: Eq
```

```rust
impl<let N: u32> Eq for MembershipWitness<N>
```

```rust
pub fn eq(_self: Self, _other: Self) -> bool
```

```rust
impl<let N: u32> Serialize for MembershipWitness<N>
```

```rust
pub fn serialize(self) -> [Field; N + 1]
```

```rust
pub fn stream_serialize<let K: u32>(self, writer: &mut Writer<K>)
```
