Struct UnifiedMemory 

pub struct UnifiedMemory<C> { /* private fields */ }

The kernel’s memory manager, wrapping a page cache.

Generic over the cache type; the bound lives on the impl blocks that actually need it (not the struct) so UnifiedMemory<C> also works over a cache that only implements the read-only, mmap-backed MmapPageSource trait rather than the full read/write UnifiedPageCache.

Implementations

impl<C> UnifiedMemory<C>

pub fn new(cache: C) -> Self

Wraps a page cache.

pub fn into_cache(self) -> C

Consumes the manager, returning the wrapped cache.

impl<C: UnifiedPageCache> UnifiedMemory<C>

pub fn map_read( &mut self, cap: &Capability, block_id: u64, ) -> Result<&Page, CacheError>

Maps a page for reading (capability-checked). Same bytes the storage engine holds.

pub fn map_write( &mut self, cap: &Capability, block_id: u64, ) -> Result<&mut Page, CacheError>

Maps a page for writing (capability-checked).

pub fn unmap(&mut self, block_id: u64)

Releases a mapping.
