Enum EvmIrStackOp 

pub enum EvmIrStackOp {
    Dup(u8),
    Swap(u8),
    Pop,
}

A materialized physical EVM stack operation.

These are modeled distinctly from generic operation mnemonics so stack scheduling can target EVM IR and later EVM IR passes can optimize the exact DUP/SWAP/POP sequence before final assembly.

Variants

Dup(u8)

EVM DUP1 through DUP16.

Swap(u8)

EVM SWAP1 through SWAP16.

Pop

EVM POP.

Implementations

impl EvmIrStackOp

pub const fn dup(n: u8) -> Option<Self>

Creates a DUP<N> operation.

pub const fn swap(n: u8) -> Option<Self>

Creates a SWAP<N> operation.

pub const fn stack_effect(self) -> EvmIrStackEffect

Returns this operation’s stack effect.

Trait Implementations

impl Clone for EvmIrStackOp

fn clone(&self) -> EvmIrStackOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EvmIrStackOp

impl Debug for EvmIrStackOp

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

Formats the value using the given formatter.

impl Eq for EvmIrStackOp

impl Hash for EvmIrStackOp

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,

impl PartialEq for EvmIrStackOp

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