Struct EfficientStateVector 

pub struct EfficientStateVector { /* private fields */ }

A memory-efficient storage for large quantum state vectors with SciRS2 enhancements

This provides memory-efficient storage and operations for quantum states, with support for chunk-based processing, buffer pools, and advanced memory management.

Implementations

impl EfficientStateVector

pub fn new(num_qubits: usize) -> QuantRS2Result<Self>

Create a new efficient state vector for the given number of qubits

pub fn with_config( num_qubits: usize, config: MemoryConfig, ) -> QuantRS2Result<Self>

Create a new efficient state vector with custom memory configuration

pub fn new_gpu_optimized(num_qubits: usize) -> QuantRS2Result<Self>

Create state vector optimized for GPU operations

pub fn num_qubits(&self) -> usize

Get the number of qubits

pub fn size(&self) -> usize

Get the size of the state vector

pub fn data(&self) -> &[Complex64]

Get a reference to the state data

pub fn data_mut(&mut self) -> &mut [Complex64]

Get a mutable reference to the state data

pub fn normalize(&mut self) -> QuantRS2Result<()>

Normalize the state vector using SciRS2 optimizations

pub fn get_probability(&self, basis_state: usize) -> QuantRS2Result<f64>

Calculate the probability of measuring a specific basis state

pub fn process_chunks<F>( &mut self, chunk_size: usize, f: F, ) -> QuantRS2Result<()>

where F: Fn(&mut [Complex64], usize) + Send + Sync,

Apply a function to chunks of the state vector with SciRS2 optimization

This is useful for operations that can be parallelized or when working with states too large to fit in cache.

pub fn optimize_memory_layout(&mut self) -> QuantRS2Result<()>

Optimize memory layout for better cache performance

pub fn clone_optimized(&self) -> QuantRS2Result<Self>

Clone state vector with memory optimization

pub fn get_config(&self) -> &MemoryConfig

Get memory configuration

pub fn update_config(&mut self, config: MemoryConfig) -> QuantRS2Result<()>

Update memory configuration

impl EfficientStateVector

pub fn memory_stats(&self) -> StateMemoryStats

Get enhanced memory usage statistics

pub fn memory_efficiency_report(&self) -> String

Get memory efficiency report
