Struct ethereumvm::SeqMemory

pub struct SeqMemory { /* fields omitted */ }

A sequencial memory. It uses Rust's Vec for internal representation.

Methods

impl SeqMemory

pub fn len(&self) -> usize

Get the length of the current effective memory range.

pub fn is_empty(&self) -> bool

Return true if current effective memory range is zero

Trait Implementations

impl Memory for SeqMemory

fn new(memory_limit: usize) -> Self

Create new SeqMemory instance with supplied Patch

fn check_write(&self, index: U256) -> Result<(), NotSupportedError>

Check whether write on this index would result in an error. If this function returns Ok, then both write and write_raw on this index should succeed.

fn check_write_range(
    &self,
    start: U256,
    len: U256
) -> Result<(), NotSupportedError>

Check whether write on the given index range would result in an error. If this function returns Ok, then both write and write_raw on the given index range should succeed.

fn write(&mut self, index: U256, value: M256) -> Result<(), NotSupportedError>

Write value into the index.

fn write_raw(&mut self, index: U256, value: u8) -> Result<(), NotSupportedError>

Write only one byte value into the index.

fn read(&self, index: U256) -> M256

Read value from the index.

fn read_raw(&self, index: U256) -> u8

Read only one byte value from the index.
