Struct Dup 

pub struct Dup<const N: u8> { /* private fields */ }

Duplicate stack items. The N constant signifies the type of the DUP opcode (e.g. Dup<16> => DUP16).

Implementations

impl<const N: u8> Dup<N>

pub const fn new() -> Self

Create a new DUP instruction with the specified type.

Example

let dup: Dup<10> = Dup::new();

This will fail to compile if the instruction is not correct.

let dup: Dup<30> = Dup::new(); // compile fail!

Trait Implementations

impl<const N: u8> Clone for Dup<N>

fn clone(&self) -> Dup<N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const N: u8> Debug for Dup<N>

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

Formats the value using the given formatter.

impl<const N: u8> Default for Dup<N>

fn default() -> Self

Returns the “default value” for a type.

impl<const N: u8> Display for Dup<N>

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

Formats the value using the given formatter.

impl<const N: u8> Hash for Dup<N>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<const N: u8> Instruction for Dup<N>

fn opcode(&self) -> OpCode

Return the operation code associated with this instruction.

fn is_push(&self) -> bool

Returns a value signifying whether this instruction is of the type PUSHx.

fn is_dup(&self) -> bool

Returns a value signifying whether this instruction is of the type DUPx.

fn is_swap(&self) -> bool

Returns a value signifying whether this instruction is of the type SWAPx.

fn is_log(&self) -> bool

Returns a value signifying whether this instruction is of the type LOGx.

fn is_terminator(&self) -> bool

Returns true for instructions that terminate execution of the smart contract.

impl<const N: u8> PartialEq for Dup<N>

fn eq(&self, other: &Dup<N>) -> 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.
