pub enum BTreePageType {
    InteriorIndex = 2,
    InteriorTable = 5,
    LeafIndex = 10,
    LeafTable = 13,
}

B-tree page types.

Variants

InteriorIndex = 2

LeafIndex = 10

Leaf index B-tree page.

LeafTable = 13

Leaf table B-tree page.

Implementations

impl BTreePageType

pub const fn from_byte(b: u8) -> Option<Self>

Parse from the raw byte value at the start of a B-tree page header.

pub const fn is_leaf(self) -> bool

Whether this is a leaf page (no children).

pub const fn is_interior(self) -> bool

Whether this is an interior (non-leaf) page.

pub const fn is_table(self) -> bool

Whether this is a table B-tree (INTKEY) page.

pub const fn is_index(self) -> bool

Whether this is an index B-tree (BLOBKEY) page.

Trait Implementations

impl Clone for BTreePageType

fn clone(&self) -> BTreePageType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BTreePageType

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

Formats the value using the given formatter.

impl Hash for BTreePageType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BTreePageType

fn eq(&self, other: &BTreePageType) -> 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.
