Enum Value 

#[non_exhaustive]
pub enum Value {
    Null,
    Bool(bool),
    Int(i64),
    Float(f64),
    String(String),
    Bytes(Vec<u8>),
    Date(NaiveDate),
    Time(NaiveTime),
    DateTime(NaiveDateTime),
    Timestamp(DateTime<Utc>),
    Uuid(Uuid),
    Json(Value),
    Unknown(String),
}

Engine-agnostic representation of a database value.

Drivers convert their native types into Value when reading rows and in the opposite direction when binding parameters. Values that cannot be expressed in one of the structured variants are preserved in Value::Unknown as their textual rendering.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Null

Bool(bool)

Int(i64)

Float(f64)

String(String)

Bytes(Vec<u8>)

Date(NaiveDate)

Time(NaiveTime)

DateTime(NaiveDateTime)

Timestamp(DateTime<Utc>)

Uuid(Uuid)

Json(Value)

Unknown(String)

Implementations

impl Value

pub const fn is_null(&self) -> bool

pub fn render(&self) -> String

Render the value as a plain string suitable for display in a grid.

Delegates to std::fmt::Display which writes straight to the formatter — no intermediate allocation for the integer/float/date paths (L1).

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Value

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Value

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

Formats the value using the given formatter.

impl Serialize for Value

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
