Enum ValueType 

pub enum ValueType {
    String,
    Number,
    Boolean,
    Null,
    Json,
    Int,
}

The logical type of a column (or a literal), mirroring the JS ValueType (zero-schema/table-schema.ts): the five types Zero stores, plus the opt-in exact-integer plane (design 226). It drives the SQLite value boundary — to_sqlite_param (boolean→0/1, json→serialized TEXT) and from_sqlite (ty-directed col() conversion, the number safe-int bound check). The leaf maps each to a crate::value storage class.

Number is the f64 plane: an out-of-safe-range integer in a Number column is an error, not a silent widening. Int is the declared exact-i64 plane (226 §4): its cells are NULL or SQLite storage class INTEGER, carried as OwnedValue::Int end to end with no round-trip bound. No decltype maps to Int yet — BIGINT/INT8 stay refused until 226 Stage C4 lifts the refusal — so today it is reachable only by explicit declaration (embedded SourceSchema::with_column_types, typed ColumnDefs).

Json

Int

The exact-i64 column plane (design 226): NULL-or-INTEGER storage class, no f64 round-trip requirement.

Trait Implementations

impl Clone for ValueType

fn clone(&self) -> ValueType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueType

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

Formats the value using the given formatter.

impl PartialEq for ValueType

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

impl Copy for ValueType
