Struct BTreeBasePage 

pub struct BTreeBasePage { /* private fields */ }

Implementations

impl BTreeBasePage

pub fn new(pid: &BTreePageID) -> BTreeBasePage

pub fn empty_page_data() -> Vec<u8>

Static method to generate a byte array corresponding to an empty BTreePage.

Used to add new, empty pages to the file.

Passing the results of this method to the following constructors will create a BTreePage with no valid entries in it.

• BTreeInternalPage
• BTreeLeafPage

pub fn is_empty_page(bytes: &[u8]) -> bool
