Struct BoundField 

Source 
pub struct BoundField<S: Schema, Owner: Model<Schema = S>, V> { /* private fields */ }
Expand description

One generated field resolved against one session binding occurrence.

The token retains its declaring owner; owner/binding compatibility is enforced against the installed registry when the predicate is lowered, before any I/O.

Implementations§

Source§

impl<S, Owner, V> BoundField<S, Owner, V>
where S: Schema, Owner: Model<Schema = S>, V: NumericValued,

Source

pub fn sum(self) -> Agg<S, V::Reduced>

Source

pub fn min(self) -> Agg<S, Option<V::Reduced>>

The smallest of this field’s values; absent on an empty ungrouped stream.

Source

pub fn max(self) -> Agg<S, Option<V::Reduced>>

The largest of this field’s values; absent on an empty ungrouped stream.

Source

pub fn mean(self) -> Agg<S, Option<f64>>

The arithmetic mean of this field’s values; absent on an empty ungrouped stream.

Source

pub fn median(self) -> Agg<S, Option<f64>>

The statistical median of this field’s values; absent on an empty ungrouped stream.

Source

pub fn stddev(self) -> Agg<S, Option<f64>>

The sample standard deviation of this field’s values; absent when fewer than two values are witnessed on an ungrouped stream.

Source§

impl<S: Schema, Owner: Model<Schema = S>, V> BoundField<S, Owner, V>

Inequality against a canonical literal of the field’s scalar domain.

Text containment against bounded canonical text; admitted only for text field domains.

Source

where V: TextValued,

Anchored text prefix against bounded canonical text; admitted only for text field domains.

Anchored text suffix against bounded canonical text; admitted only for text field domains.

Source

pub fn eq_field<Owner2, V2>( self, other: BoundField<S, Owner2, V2>, ) -> Predicate<S>
where Owner2: Model<Schema = S>, V: QueryValued, V2: QueryValued<Domain = V::Domain>,

Compare for equality against another bound field in the same canonical scalar domain; the comparison carries no literal.

Source

pub fn ne_field<Owner2, V2>( self, other: BoundField<S, Owner2, V2>, ) -> Predicate<S>
where Owner2: Model<Schema = S>, V: QueryValued, V2: QueryValued<Domain = V::Domain>,

Compare as less than another bound field in the same ordered canonical scalar domain.

Source

pub fn le_field<Owner2, V2>( self, other: BoundField<S, Owner2, V2>, ) -> Predicate<S>
where Owner2: Model<Schema = S>, V: QueryValued + OrderedValued, V2: QueryValued<Domain = V::Domain> + OrderedValued,

Compare as less than or equal to another bound field in the same ordered canonical scalar domain.

Source

pub fn gt_field<Owner2, V2>( self, other: BoundField<S, Owner2, V2>, ) -> Predicate<S>

where Owner2: Model<Schema = S>, V: QueryValued + OrderedValued, V2: QueryValued<Domain = V::Domain> + OrderedValued,

Compare as greater than or equal to another bound field in the same ordered canonical scalar domain.

Source

pub fn asc(self) -> Order<S>

Order ascending by this bound field; missing keys fail closed unless an explicit missing-value policy is admitted.

Source

pub fn desc(self) -> Order<S>

Order descending by this bound field; missing keys fail closed unless an explicit missing-value policy is admitted.
