Struct WorkingBuffer 

pub struct WorkingBuffer { /* private fields */ }

A reusable working buffer for temporary storage

This buffer manages raw memory that can be interpreted as different types (f64 or Complex) depending on the operation. It automatically grows when more space is needed.

Safety

This struct manages raw memory and must be used carefully:

• The buffer is aligned for Complex (16 bytes)
• When casting to different types, ensure alignment requirements are met

Implementations

impl WorkingBuffer

pub fn new() -> Self

Create a new empty working buffer

pub fn with_capacity_bytes(capacity_bytes: usize) -> Self

Create a new working buffer with initial capacity (in bytes)

pub fn ensure_capacity_bytes(&mut self, required_bytes: usize)

Ensure the buffer has at least the specified capacity in bytes

If the current capacity is insufficient, the buffer is reallocated. Existing data is NOT preserved.

pub fn ensure_capacity<T>(&mut self, count: usize)

Ensure the buffer can hold at least count elements of type T

pub unsafe fn as_f64_slice_mut(&mut self, count: usize) -> &mut [f64]

Get the buffer as a mutable slice of f64

Safety

Caller must ensure:

• The buffer has enough capacity for count f64 elements
• No other references to this buffer exist

pub unsafe fn as_complex_slice_mut( &mut self, count: usize, ) -> &mut [Complex<f64>]

Get the buffer as a mutable slice of Complex

Safety

Caller must ensure:

• The buffer has enough capacity for count Complex elements
• No other references to this buffer exist

pub fn as_ptr(&self) -> *mut u8

Get the raw pointer

pub fn capacity_bytes(&self) -> usize

Get current capacity in bytes
