Struct sqlite_rs::btree::header::BtreePageHeader

pub struct BtreePageHeader { /* private fields */ }

B-tree Page Header Format (8 Bytes)

Offset	Size	Description
0	1	The one-byte flag at offset 0 indicating the b-tree page type.
1	2	The two-byte integer at offset 1 gives the start of the first freeblock on the page, or is zero if there are no freeblocks.
3	2	The two-byte integer at offset 3 gives the number of cells on the page.
5	2	The two-byte integer at offset 5 designates the start of the cell content area. A zero value for this integer is interpreted as 65536.
7	1	The one-byte integer at offset 7 gives the number of fragmented free bytes within the cell content area.
8	4	The four-byte page number at offset 8 is the right-most pointer. This value appears in the header of interior b-tree pages only and is omitted from all other pages.

Trait Implementations

impl Debug for BtreePageHeader

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

Formats the value using the given formatter.

impl Name for BtreePageHeader

const NAME: &'static str = _

impl PartialEq<BtreePageHeader> for BtreePageHeader

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<&[u8]> for BtreePageHeader

type Error = SQLiteError

The type returned in the event of a conversion error.

fn try_from(bytes: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.
