Enum PushOpcode 

pub enum PushOpcode {
    Push1,
    Push2,
    Push3,
}

Push opcode for jump instructions

Variants

Push1

PUSH1 opcode (0x60) - pushes 1 byte onto stack

Push2

PUSH2 opcode (0x61) - pushes 2 bytes onto stack

Push3

PUSH3 opcode (0x62) - pushes 3 bytes onto stack; needed for offsets beyond 64 KiB, which initcode can reach from Amsterdam (EIP-7954)

Implementations

impl PushOpcode

pub fn to_hex(&self) -> &'static str

Convert to hex string representation

pub fn byte_size(&self) -> usize

Get the number of bytes this push opcode accepts (not including the opcode itself)

pub fn can_represent(&self, value: usize) -> bool

Check if a value can be represented by this push opcode

pub fn optimal_for(value: usize) -> Self

Get the optimal push opcode for a given value

pub fn format_value(&self, value: usize) -> String

Formats a value as the zero-padded push data of this opcode

pub fn from_hex(s: &str) -> Option<Self>

Parse from hex string (for tests and compatibility)

Trait Implementations

impl Clone for PushOpcode

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Eq for PushOpcode

impl Ord for PushOpcode

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for PushOpcode

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for PushOpcode

fn partial_cmp(&self, other: &Self) -> 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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
