Page Size (2 Bytes)

The two-byte value beginning at offset 16 determines the page size of the database. For Sqlite versions 3.7.0.1 (2010-08-04) and earlier, this value is interpreted as a big-endian integer and must be a power of two between 512 and 32768, inclusive. Beginning with Sqlite version 3.7.1 (2010-08-23), a page size of 65536 bytes is supported. The value 65536 will not fit in a two-byte integer, so to specify a 65536-byte page size, the value at offset 16 is 0x00 0x01. This value can be interpreted as a big-endian 1 and thought of as a magic number to represent the 65536 page size. Or one can view the two-byte field as a little endian number and say that it represents the page size divided by 256. These two interpretations of the page-size field are equivalent.

Implementations

impl PageSize

pub const MAX: Self = Self::L65536

pub const fn as_usize(&self) -> usize

Trait Implementations

impl Clone for PageSize

fn clone(&self) -> PageSize

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PageSize

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

Formats the value using the given formatter.

impl Default for PageSize

fn default() -> PageSize

Returns the “default value” for a type.

impl From<&PageSize> for u32

fn from(value: &PageSize) -> Self

Converts to this type from the input type.

impl Name for PageSize

const NAME: &'static str = "PageSize"

impl PartialEq for PageSize

fn eq(&self, other: &PageSize) -> 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 Eq for PageSize
