Struct RuntimeMemory 

pub struct RuntimeMemory<M: Memory> { /* private fields */ }

RuntimeMemory

Exclusive non-cloneable allocation lease. IO trusts custody between checked boundaries; growth commits the directory before publishing its new extent. A detached lease retains the backing claim until it is dropped.

Implementations

impl<M: Memory> RuntimeMemory<M>

pub fn size(&self) -> u64

Logical page extent.

pub fn grow(&self, pages: u64) -> Result<u64, RuntimeGrowError>

Reserve additional zero-filled logical pages without exposing backing.

Errors

Rejects arithmetic overflow, resource limits, backing refusal, poisoned ownership, or invalid directory state.

pub fn read(&self, offset: u64, bytes: &mut [u8])

Read a completely bounds-checked logical range.

pub fn write(&self, offset: u64, bytes: &[u8])

Write a completely bounds-checked logical range.

Trait Implementations

impl<M: Memory> Memory for RuntimeMemory<M>

fn size(&self) -> u64

Current extent in 65,536-byte pages.

fn grow(&self, pages: u64) -> i64

Add zero-filled pages, or return -1 on refusal.

fn read(&self, offset: u64, bytes: &mut [u8])

Read an admitted byte range.

fn write(&self, offset: u64, bytes: &[u8])

Write an admitted byte range. Native writes need not be transactional.
