Struct Page 

pub struct Page { /* private fields */ }

An owned, page-sized buffer. Lives in the cache’s Vec<Frame> and is reused across loads — the pager never allocates a new Page on the read hot path (Rule 3).

Implementations

impl Page

pub fn zeroed() -> Self

Allocate a new zeroed page. Called only during cache initialisation; never on the read hot path.

pub fn as_bytes(&self) -> &[u8; 4096]

Get the page as a byte slice.

pub fn as_bytes_mut(&mut self) -> &mut [u8; 4096]

Get the page as a mutable byte slice.

pub fn zero(&mut self)

Zero the entire page in place. Used when the cache evicts a frame and prepares it for reuse with new contents.
