Enum Value 

pub enum Value {
    Null,
    Bool(bool),
    Int(i64),
    Real(f64),
    Text(String),
    Blob(Vec<u8>),
    Timestamp(OffsetDateTime),
    Json(Value),
    Uuid(Uuid),
    Array(Vec<Value>),
}

A single database value, independent of any backend.

This is the common currency between the query layer and a driver: query parameters are lowered into Values, and result columns are read back as Values before being converted into Rust types via FromValue.

Examples

use tork_orm_core::Value;

let name = Value::Text("alice".to_string());
let active = Value::Bool(true);
assert!(matches!(name, Value::Text(_)));
assert!(matches!(active, Value::Bool(true)));

Variants

Null

SQL NULL.

Bool(bool)

A boolean, stored as an integer 0 or 1 by backends without a native type.

Int(i64)

A signed 64-bit integer.

Real(f64)

A 64-bit floating point number.

Text(String)

UTF-8 text.

Blob(Vec<u8>)

Raw bytes.

Timestamp(OffsetDateTime)

A timestamp, rendered to and parsed from RFC 3339 text by default.

Json(Value)

A JSON document (PostgreSQL json/jsonb).

Uuid(Uuid)

A UUID (PostgreSQL uuid).

Array(Vec<Value>)

An array of values (PostgreSQL type[]), each element a Value.

Implementations

impl Value

pub fn is_null(&self) -> bool

Returns true if this value is Value::Null.

Examples

use tork_orm_core::Value;

assert!(Value::Null.is_null());
assert!(!Value::Int(1).is_null());

Trait Implementations

impl BindValue for Value

fn to_value(&self) -> Value

Lowers this value into a bound parameter.

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 FromValue for Value

fn from_value(value: Value) -> Result<Self>

Attempts to read this type from a database value.

impl<T> IntoAssignExpr<T> for Value

fn into_assign_expr(self) -> Expr

Converts self into an assignment expression.

impl PartialEq for Value

fn eq(&self, other: &Value) -> 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 StructuralPartialEq for Value

impl ToSql for Value

Implements binding so a Value can be passed as a SQLite parameter.

fn to_sql(&self) -> Result<ToSqlOutput<'_>>

Converts Rust value to SQLite value
