Struct MemoryView 

pub struct MemoryView { /* private fields */ }

Zero-copy memory view for WASM state inspection

Per spec: “Eliminates bincode serialization per-frame (Muda)”

Safety

The memory view is only valid while the WASM instance is alive. Do not store references across frame boundaries.

Implementations

impl MemoryView

pub fn new(size: usize) -> Self

Create a new memory view

pub fn with_entity_table(self, offset: usize, count: usize) -> Self

Configure entity table location

pub fn with_component_arrays(self, offset: usize) -> Self

Configure component arrays location

pub const fn size(&self) -> usize

Get the memory size

pub const fn entity_count(&self) -> usize

Get entity count

pub const fn entity_table_offset(&self) -> usize

Get entity table offset

pub const fn component_arrays_offset(&self) -> usize

Get component arrays offset

pub unsafe fn read_at<T: Copy>( &self, memory: &[u8], offset: usize, ) -> ProbarResult<T>

Read a value at the given offset from a memory slice

Safety

Caller must ensure:

• offset + size_of::<T>() <= memory.len()
• The memory at offset contains a valid T

pub fn read_slice<'a>( &self, memory: &'a [u8], offset: usize, len: usize, ) -> ProbarResult<&'a [u8]>

Read a slice from memory

Safety

Caller must ensure the memory region is valid

Trait Implementations

impl Debug for MemoryView

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
