Struct Aggregate 

pub struct Aggregate {
    pub qname: QualifiedName,
    pub arg_types: Vec<ColumnType>,
    pub state_type: ColumnType,
    pub sfunc: QualifiedName,
    pub finalfunc: Option<QualifiedName>,
    pub initcond: Option<String>,
    pub owner: Option<Identifier>,
    pub comment: Option<String>,
}

A CREATE AGGREGATE object. Identity is (qname, arg_types).

Fields

qname: QualifiedName

Schema-qualified aggregate name.

arg_types: Vec<ColumnType>

Aggregate argument types (part of identity; aggregates are overloadable).

state_type: ColumnType

State type (STYPE).

sfunc: QualifiedName

State transition function (SFUNC) — a managed function name.

finalfunc: Option<QualifiedName>

Optional final function (FINALFUNC).

initcond: Option<String>

Optional initial condition (INITCOND), as text.

owner: Option<Identifier>

Lenient owner (None = unmanaged).

comment: Option<String>

Optional comment.

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 Eq for Aggregate

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.
