Trait Implementations

impl Clone for Aggregate

fn clone(&self) -> Aggregate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Aggregate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Aggregate

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Aggregate

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 Aggregate

fn eq(&self, other: &Aggregate) -> 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 Serialize for Aggregate

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToSql for Aggregate

fn to_sql(&self) -> String

impl<'a> TryFrom<AggregateNode<'a>> for Aggregate

type Error = Error

The type returned in the event of a conversion error.

fn try_from(aggr_node: AggregateNode<'a>) -> Result<Self>

Performs the conversion.

impl Eq for Aggregate

impl StructuralPartialEq for Aggregate
