Enum ValueType 

pub enum ValueType {
    Integer,
    Numeric,
    Float,
    Text,
    Blob,
    Null,
}

Represents the value type category for type inference and coercion

This enum is used to determine the result type of operations based on the SQL mode’s type system behavior.

Variants

Integer

Integer type (whole numbers)

Numeric

Exact decimal type (MySQL DECIMAL/NUMERIC)

This represents exact decimal arithmetic with fixed precision. MySQL uses this for division results to preserve precision.

Float

Approximate floating-point type (MySQL FLOAT/DOUBLE, SQLite REAL)

This represents IEEE 754 floating-point numbers with potential rounding errors but better performance for large ranges.

Text

Text/String type

Blob

Binary blob type

Null

NULL value

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

Formats the value using the given formatter.

impl Hash for ValueType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
