Enum ColumnTypeName 

pub enum ColumnTypeName {
    SmallInt,
    Int,
    BigInt,
    Float,
    Text,
    Varchar(u32),
    Char(u32),
    Bool,
    Vector {
        dim: u32,
        encoding: VecEncoding,
    },
    Numeric(u8, u8),
    Date,
    Timestamp,
    Json,
}

SQL-level type names. The mapping to the storage runtime’s DataType happens in spg-engine — keeping spg-sql free of storage deps.

Variants

SmallInt

Int

BigInt

Float

Text

Varchar(u32)

VARCHAR(N) — TEXT capped at N Unicode characters.

Char(u32)

CHAR(N) — TEXT right-padded with spaces to exactly N characters.

Bool

Vector

pgvector fixed-dimension VECTOR(N). v6.0.1 added the USING <encoding> clause; omitting it surfaces as encoding = VecEncoding::F32 (the pre-v6 default).

Fields

dim: u32

encoding: VecEncoding

Numeric(u8, u8)

NUMERIC / NUMERIC(p) / NUMERIC(p, s) — exact decimal. Bare NUMERIC and NUMERIC(p) both surface with scale=0.

Date

DATE — calendar day, no time-of-day component.

Timestamp

TIMESTAMP / MySQL DATETIME — instant with microsecond precision.

Json

v4.9 JSON / JSONB — text-backed JSON document. No parse- time validation; the engine round-trips the literal verbatim.

Trait Implementations

impl Clone for ColumnTypeName

fn clone(&self) -> ColumnTypeName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ColumnTypeName

impl Debug for ColumnTypeName

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

Formats the value using the given formatter.

impl Display for ColumnTypeName

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

Formats the value using the given formatter.

impl Eq for ColumnTypeName

impl PartialEq for ColumnTypeName

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