Struct Zero

pub struct Zero<T>(/* private fields */);

Enforce value to be zero. This type will always encode as evm zero, and will fail on decoding if not zero.

impl<T: AbiType> AbiType for Zero<T>

const SIGNATURE: SignatureUnit = T::SIGNATURE

Signature for Ethereum ABI.

const HEAD_WORDS: u32 = T::HEAD_WORDS

How many AbiWords static data this type should occupy

const IS_DYNAMIC: bool = T::IS_DYNAMIC

Is this a dynamic type, per spec.

fn signature() -> &'static str

Signature as str.

impl<T: Clone> Clone for Zero<T>

fn clone(&self) -> Zero<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for Zero<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Default for Zero<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: PartialEq> PartialEq for Zero<T>

fn eq(&self, other: &Zero<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
