Struct MemoryManager 

pub struct MemoryManager<P>
where
    P: MemoryProvider,
{ /* private fields */ }

The memory manager handles page-level memory operations on top of a MemoryProvider.

Implementations

impl<P> MemoryManager<P>

where P: MemoryProvider,

pub fn init(provider: P) -> Self

Initializes the memory manager and allocates the header and reserved pages.

Panics

Panics if the memory provider fails to initialize.

pub const fn acl_page(&self) -> Page

Returns the ACL page number.

pub const fn schema_page(&self) -> Page

Returns the schema page.

pub fn write_at_raw( &mut self, page: Page, offset: PageOffset, buf: &[u8], ) -> MemoryResult<()>

Writes raw bytes at the specified page and offset, bypassing alignment and encoding checks.

This is used by the journal rollback path which already holds pre-captured byte buffers.

Trait Implementations

impl<P> MemoryAccess for MemoryManager<P>

where P: MemoryProvider,

fn page_size(&self) -> u64

Returns the size of a single memory page.

fn allocate_page(&mut self) -> MemoryResult<Page>

Allocates an additional page in memory and returns its number.

fn read_at<D>(&self, page: Page, offset: PageOffset) -> MemoryResult<D>

where D: Encode,

Reads a typed value from the specified page and offset.

fn write_at<E>( &mut self, page: Page, offset: PageOffset, data: &E, ) -> MemoryResult<()>

where E: Encode,

Writes a typed value at the specified page and offset.

fn zero<E>( &mut self, page: Page, offset: PageOffset, data: &E, ) -> MemoryResult<()>

where E: Encode,

Zeros out the region occupied by data at the specified page and offset.

fn read_at_raw( &self, page: Page, offset: PageOffset, buf: &mut [u8], ) -> MemoryResult<usize>

Reads raw bytes into buf at the specified page and offset.
