    Int32(Option<i32>),
    Int64(Option<i64>),
    Float(Option<f32>),
    Double(Option<f64>),

}

A value we must parameterize for the prepared statement. Null values should be defined by their corresponding type variants with a None value for best compatibility.

Variants

Int32(Option<i32>)

32-bit signed integer.

Int64(Option<i64>)

64-bit signed integer.

Float(Option<f32>)

32-bit floating point.

Double(Option<f64>)

64-bit floating point.

Text(Option<Cow<'a, str>>)

String value.

Enum(Option<EnumVariant<'a>>, Option<EnumName<'a>>)

Database enum value. The optional EnumName is only used on PostgreSQL. Read more about it here: https://github.com/prisma/prisma-engines/pull/4280

EnumArray(Option<Vec<EnumVariant<'a>>>, Option<EnumName<'a>>)

Database enum array (PostgreSQL specific). We use a different variant than ValueType::Array to uplift the EnumName and have it available even for empty enum arrays.

Bytes(Option<Cow<'a, [u8]>>)

Bytes value.

Boolean(Option<bool>)

Boolean value.

Char(Option<char>)

A single character.

Array(Option<Vec<Value<'a>>>)

An array value (PostgreSQL).

Numeric(Option<BigDecimal>)

A numeric value.

Json(Option<Value>)

A JSON value.

Xml(Option<Cow<'a, str>>)

A XML value.

Uuid(Option<Uuid>)

An UUID value.

DateTime(Option<DateTime<Utc>>)

A datetime value.

Date(Option<NaiveDate>)

A date value.

Time(Option<NaiveTime>)

A time value.
