Struct DynamicValue 

pub struct DynamicValue {
    pub type_: Type,
    pub value: Value,
}

A row of a Variant, Dynamic or Geometry column: the value and its actual type.

Fields

type_: Type

value: Value

Implementations

impl DynamicValue

pub fn new(type_: Type, value: Value) -> Self

Trait Implementations

impl Clone for DynamicValue

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DynamicValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DynamicValue

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for DynamicValue

impl FromSql for DynamicValue

A Variant/Dynamic/Geometry row with its actual type (LineString stays LineString); any other column gives its own type. NULL rows need an Option<DynamicValue>.

fn from_sql(type_: &Type, value: Value) -> Result<Self>

fn from_sql_column(type_: &Type, value: Value) -> Result<Self>

Converts a value as read from a column of type_. By default the wrappers listed in from_sql_resolved are looked through first; types that keep the raw value (like Value) override this.

impl Hash for DynamicValue

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 DynamicValue

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for DynamicValue

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for DynamicValue

impl ToSql for DynamicValue

fn to_sql(self, _type_hint: Option<&Type>) -> Result<Value>
