fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Operation for IsZero

type Immediate = Void

The type of the immediate argument for this operation.

type ImmediateRef = Void

The return root type of Operation::immediate_mut and Operation::immediate.

type Code = IsZero

The return type of Operation::code.

fn immediate(&self) -> Option<&Self::ImmediateRef>

Get a shared reference to the immediate argument of this operation, if one exists.

fn immediate_mut(&mut self) -> Option<&mut Self::ImmediateRef>

Get a mutable reference to the immediate argument of this operation, if one exists.

fn into_immediate(self) -> Option<Self::Immediate>

Consume this operation and return its immediate argument, if one exists.

fn code(&self) -> Self::Code

The action (opcode) of this operation, without any immediates.

fn extra_len(&self) -> usize

Length of immediate argument.

fn mnemonic(&self) -> &str

Human-readable name for this operation.

fn is_jump(&self) -> bool

Returns true if the current instruction changes the program counter (other than incrementing it.)

fn is_jump_target(&self) -> bool

Returns true if the current instruction is a valid destination for jumps.

fn is_exit(&self) -> bool

Returns true if the current instruction causes the EVM to stop executing the contract.

fn pops(&self) -> usize

How many stack elements this instruction pops.

fn pushes(&self) -> usize

How many stack elements this instruction pushes.

fn code_byte(&self) -> u8

The byte (opcode) that indicates this operation.

impl Ord for IsZero

fn cmp(&self, other: &IsZero) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for IsZero

fn eq(&self, other: &IsZero) -> 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.

impl PartialOrd for IsZero

fn partial_cmp(&self, other: &IsZero) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
