Struct Push 

pub struct Push<const N: usize>(/* private fields */);

Place item on stack. The N constant signifies the type of the PUSH opcode (e.g. Push<32> => PUSH32).

Implementations

impl<const N: usize> Push<N>

pub const fn new(immediate: [u8; N]) -> Self

Create a new PUSH instruction with an immediate value.

Example

let push: Push<32> = Push::new([0; 32]);

This will fail to compile if the size of the immediate value is greater than 32.

let push = Push::new([0; 33]); // compile fail!

pub const fn immediate(&self) -> &[u8; N]

Get a reference to the immediate value.

Example

let push = Push::new([1, 3, 3, 7]);
assert_eq!(push.immediate(), &[1, 3, 3, 7]);

pub const fn size(&self) -> u8

Return the size of the immediate value.

Example

fn push_size<const N: usize>(push: &Push<N>) {
    assert_eq!(push.size() as usize, N);
}

Trait Implementations

impl<const N: usize> Clone for Push<N>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const N: usize> Debug for Push<N>

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

Formats the value using the given formatter.

impl<const N: usize> Display for Push<N>

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

Formats the value using the given formatter.

impl<const N: usize> Hash for Push<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: usize> Instruction for Push<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: usize> PartialEq for Push<N>

fn eq(&self, other: &Push<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.
