Enum DataType 

pub enum DataType {
    Integer,
    Text,
    Real,
    Bool,
    Vector(usize),
    None,
    Invalid,
}

SQLRite data types Mapped after SQLite Data Type Storage Classes and SQLite Affinity Type (Datatypes In SQLite Version 3)[https://www.sqlite.org/datatype3.html]

Vector(dim) is the Phase 7a addition — a fixed-dimension dense f32 array. The dimension is part of the type so a VECTOR(384) column rejects [0.1, 0.2, 0.3] at INSERT time as a clean type error rather than silently storing the wrong shape.

Variants

Integer

Text

Real

Bool

Vector(usize)

Dense f32 vector of fixed dimension. The usize is the column’s declared dimension; every value stored in the column must have exactly that many elements.

None

Invalid

Implementations

impl DataType

pub fn new(cmd: String) -> DataType

Constructs a DataType from the wire string the parser produces. Pre-Phase-7 the strings were one-of "integer" | "text" | "real" | "bool" | "none". Phase 7a adds "vector(N)" (case-insensitive, N a positive integer) for the new vector column type — encoded in-band so we don’t have to plumb a richer type through the existing string-based ParsedColumn pipeline.

pub fn to_wire_string(&self) -> String

Inverse of new — returns the canonical lowercased wire string for this DataType. Used by the parser to round-trip VECTOR(N) → DataType::Vector(N) → "vector(N)" into ParsedColumn::datatype so the rest of the pipeline keeps working with strings.

Trait Implementations

impl Clone for DataType

fn clone(&self) -> DataType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataType

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

Formats the value using the given formatter.

impl Display for DataType

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

Formats the value using the given formatter.

impl PartialEq for DataType

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