[][src]Struct evm::Memory

pub struct Memory { /* fields omitted */ }

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


impl Memory[src]

pub fn new(limit: usize) -> Memory[src]

pub fn limit(&self) -> usize[src]

pub fn len(&self) -> usize[src]

Get the length of the current memory range.

pub fn effective_len(&self) -> U256[src]

Get the effective length.

pub fn is_empty(&self) -> bool[src]

Return true if current effective memory range is zero.

pub fn resize_offset(
    &mut self,
    offset: U256,
    len: U256
) -> Result<(), ExitError>

pub fn resize_end(&mut self, end: U256) -> Result<(), ExitError>[src]

pub fn get(&self, offset: usize, size: usize) -> Vec<u8>[src]

Get memory region at given offset.


Value of size is considered trusted. If they're too large, the program can run out of memory, or it can overflow.

pub fn set(
    &mut self,
    offset: usize,
    value: &[u8],
    target_size: Option<usize>
) -> Result<(), ExitFatal>

Set memory region at given offset. The offset and value is considered untrusted.

pub fn copy_large(
    &mut self,
    memory_offset: U256,
    data_offset: U256,
    len: U256,
    data: &[u8]
) -> Result<(), ExitFatal>
