Enum DbValue 

pub enum DbValue {
    Null,
    Bool(bool),
    Int(i64),
    Float(f64),
    Text(String),
    Bytes(Vec<u8>),
    Date(NaiveDate),
    DateTime(NaiveDateTime),
    TimestampTz(DateTime<Utc>),
    Json(JsonValue),
    Uuid(Uuid),
    Time(NaiveTime),
    TextArray(Vec<String>),
    FloatArray(Vec<f64>),
    OptFloatArray(Vec<Option<f64>>),
}

A backend-neutral parameter value.

Construct variants directly, or use the From conversions for ergonomics — including Option<T>, which maps None to DbValue::Null:

use dbkit::DbValue;

let a: DbValue = 42i64.into();          // Int(42)
let b: DbValue = "hello".into();        // Text("hello")
let c: DbValue = Some(3.5f64).into();   // Float(3.5)
let d: DbValue = None::<i64>.into();     // Null
assert_eq!(d, DbValue::Null);

Variants

Null

SQL NULL.

Bool(bool)

Boolean.

Int(i64)

Signed 64-bit integer. Smaller integer types widen into this.

Float(f64)

64-bit floating point.

Text(String)

UTF-8 text.

Bytes(Vec<u8>)

Raw bytes (BYTEA / BLOB).

Date(NaiveDate)

SQL DATE.

DateTime(NaiveDateTime)

SQL TIMESTAMP (no time zone).

TimestampTz(DateTime<Utc>)

SQL TIMESTAMPTZ (UTC).

Json(JsonValue)

SQL JSON / JSONB.

Uuid(Uuid)

SQL UUID.

Time(NaiveTime)

SQL TIME (no time zone).

TextArray(Vec<String>)

SQL TEXT[].

FloatArray(Vec<f64>)

SQL FLOAT8[] (double precision array).

OptFloatArray(Vec<Option<f64>>)

SQL FLOAT8[] with nullable elements.
