pub struct Memory<F> {
inner: Vec<MemoryValue<F>>,
}Expand description
The VM’s memory. Memory is internally represented as a vector of values. We grow the memory when values past the end are set, extending with 0s.
Fields§
§inner: Vec<MemoryValue<F>>Implementations§
Source§impl<F: AcirField> Memory<F>
impl<F: AcirField> Memory<F>
Sourcefn get_stack_pointer(&self) -> usize
fn get_stack_pointer(&self) -> usize
Read the value from slot 0.
Panics if it’s not a U32.
Sourcefn resolve(&self, address: MemoryAddress) -> usize
fn resolve(&self, address: MemoryAddress) -> usize
Resolve an address to either:
- itself, if it’s a direct address, or
- the current stack pointer plus the offset, if it’s relative.
Returns a memory slot index.
Sourcepub fn read(&self, address: MemoryAddress) -> MemoryValue<F>
pub fn read(&self, address: MemoryAddress) -> MemoryValue<F>
Reads the numeric value at the address.
If the address is beyond the size of memory, a default value is returned.
Sourcepub fn read_ref(&self, ptr: MemoryAddress) -> MemoryAddress
pub fn read_ref(&self, ptr: MemoryAddress) -> MemoryAddress
Reads the value at the address and returns it as a direct memory address, without dereferencing the pointer itself to a numeric value.
Sourcepub fn read_slice(
&self,
address: MemoryAddress,
len: usize,
) -> &[MemoryValue<F>]
pub fn read_slice( &self, address: MemoryAddress, len: usize, ) -> &[MemoryValue<F>]
Read a contiguous slice of memory starting at address, up to len slots.
Panics if the end index is beyond the size of the memory.
Sourcepub fn write(&mut self, address: MemoryAddress, value: MemoryValue<F>)
pub fn write(&mut self, address: MemoryAddress, value: MemoryValue<F>)
Sets the value at address to value
Sourcefn resize_to_fit(&mut self, size: usize)
fn resize_to_fit(&mut self, size: usize)
Increase the size of memory fit size elements, or the current length, whichever is bigger.
Sourcepub fn write_slice(&mut self, address: MemoryAddress, values: &[MemoryValue<F>])
pub fn write_slice(&mut self, address: MemoryAddress, values: &[MemoryValue<F>])
Sets the values after address to values
Sourcepub fn values(&self) -> &[MemoryValue<F>]
pub fn values(&self) -> &[MemoryValue<F>]
Returns the values of the memory
