Struct SerialType 

pub struct SerialType(pub u64);

A SQLite record serial type code.

The mapping from code to meaning (file-format spec, “Serial Type Codes Of The Record Format”):

code	meaning	body bytes
0	NULL	0
1	int, big-endian	1
2	int	2
3	int	3
4	int	4
5	int	6
6	int	8
7	IEEE-754 float	8
8	integer 0	0
9	integer 1	0
10, 11	reserved	—
N≥12 even	BLOB	(N-12)/2
N≥13 odd	TEXT	(N-13)/2

Tuple Fields

0: u64

Implementations

impl SerialType

pub fn content_len(self) -> Option<usize>

Number of bytes this serial type occupies in the record body, or None for the reserved codes 10 and 11.

pub fn for_value(value: &Value) -> SerialType

The smallest serial type that can losslessly represent value.

This matches SQLite’s choice: small integers collapse to the 0/1 literals (codes 8/9) and otherwise to the narrowest of the 1/2/3/4/6/8-byte forms.

Trait Implementations

impl Clone for SerialType

fn clone(&self) -> SerialType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SerialType

impl Debug for SerialType

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

Formats the value using the given formatter.

impl Eq for SerialType

impl PartialEq for SerialType

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