Struct PageData 

pub struct PageData { /* private fields */ }

Raw page data as an owned byte buffer.

The length always matches the database page size. Uses Arc for cheap cloning (Copy-On-Write).

Implementations

impl PageData

pub fn zeroed(size: PageSize) -> Self

Create a zero-filled page of the given size.

pub fn from_vec(data: Vec<u8>) -> Self

Create from existing bytes. The caller must ensure the length matches the page size.

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

Get the page data as a byte slice.

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

Get the page data as a mutable byte slice.

This performs a clone if the data is shared (Copy-On-Write).

pub fn len(&self) -> usize

Get the length in bytes.

pub fn is_empty(&self) -> bool

Returns true if the page data is empty (should never be true for valid pages).

pub fn into_vec(self) -> Vec<u8>

Consume self and return the inner Vec<u8>.

If the data is shared, this clones the vector.

Trait Implementations

impl AsMut<[u8]> for PageData

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<[u8]> for PageData

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for PageData

fn clone(&self) -> PageData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PageData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PageData

fn eq(&self, other: &PageData) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
