```rust
pub struct Nullifier {
    pub value: Field,
    pub note_hash: Field,
}
```

## Fields

```rust
value: Field
```

```rust
note_hash: Field
```

## Implementations

```rust
impl Nullifier
```

```rust
pub fn count(self, counter: u32) -> Counted<Self>
```

## Trait implementations

```rust
impl Deserialize for Nullifier

pub fn deserialize(fields: [Field; 2]) -> Self
```

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

```rust
impl Empty for Nullifier
```

```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 Eq for Nullifier
```

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

```rust
impl Readable for Nullifier
```

```rust
pub fn assert_match_read_request(self, read_request: Field)
```

```rust
impl Serialize for Nullifier
