Contains

An element of a typed array equals the value (protocol version 14): the array is read through an index naming it, which keys a document once by each of its distinct elements, so the clause is an equality on that key.

ContainsAny

An element of a typed array is one of the values (protocol version 14): an In on the elements an index keys the array by. A document holding several of the values is under each of them; a documents query returns it once, at its first. On an indexOnly type each entry is a document of its own, rebuilt as one listing the element it sits under, so a documents query returns one per value the document holds.

Implementations

impl WhereOperator

pub fn allows_flip(&self) -> bool

Matches the where operator argument and returns true if it allows flip function

pub fn flip(&self) -> Result<WhereOperator, Error>

Flips the where operator

impl WhereOperator

pub const fn is_range(self) -> bool

Returns true if the where operator result is a range

pub const fn as_key_operator(self) -> Self

The operator this one keys an index level like: an element of a typed array is an index key of its own, so Contains keys like Equal and ContainsAny like In. Every other operator keys as itself.

pub const fn reads_array_elements(self) -> bool

Whether the operator reads the elements of a typed array.

pub fn eval(&self, left_value: &Value, right_value: &Value) -> bool

Shared operator evaluator for both WhereClause and ValueClause

pub fn value_shape_ok( &self, value: &Value, property_type: &DocumentPropertyType, ) -> bool

Validates that a value matches the expected shape for this operator and property type
