Struct RetainedHostMemoryRegion 

pub struct RetainedHostMemoryRegion { /* private fields */ }

An owned, bounds-checked subregion of stable host memory.

Implementations

impl RetainedHostMemoryRegion

pub fn new<T>( owner: Arc<T>, offset_bytes: usize, length_bytes: usize, ) -> Result<Self, VNextError>

where T: StableHostMemory,

pub fn bytes(&self) -> &[u8]

pub fn owner_bytes(&self) -> &[u8]

Entire stable allocation. Backends use this only to prove that a page-aligned native view enclosing Self::bytes remains within the retained owner.

pub const fn offset_bytes(&self) -> usize

pub const fn length_bytes(&self) -> usize
