Struct Locals

pub struct Locals {
    inner: SmallVec<[LocalSlot; 16]>,
}

Solidity’s implementation uses 16 slots for locals. ref: https://docs.soliditylang.org/en/v0.8.20/internals/optimizer.html#stackcompressor

Fields

inner: SmallVec<[LocalSlot; 16]>

Implementations

impl Locals

pub fn get(&self, index: usize) -> Result<&LocalSlot>

Get local from index.

pub fn get_mut(&mut self, index: usize) -> Result<&mut LocalSlot>

Get mutate local from index.

pub fn offset_of(&self, index: usize) -> Result<SmallVec<[u8; 32]>>

Get the lower significant bytes of the byte offset of a local.

• Parameter: If the local is a parameter, the offset is relative to the offset of the calldata.
• Variable: If the local is a variable, the offset is relative to the offset of the memory.

pub fn push(&mut self, slot: impl Into<LocalSlot>)

Push a local slot.

pub fn len(&self) -> usize

Get the length of locals

pub fn is_empty(&self) -> bool

If the locals are empty.

Trait Implementations

impl Debug for Locals

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

Formats the value using the given formatter.

impl Default for Locals

fn default() -> Locals

Returns the “default value” for a type.
