Implementations

impl<'a> WhereClause

pub fn is_identifier(&self) -> bool

Returns true if the WhereClause is an identifier

pub fn in_values(&self) -> QuerySyntaxValidationResult<Cow<'_, Vec<Value>>>

Returns the where clause in values if they are an array of values, else an error

pub fn less_than(&self, other: &Self, allow_eq: bool) -> Result<bool, Error>

Returns true if the less than where clause is true

pub fn from_components(clause_components: &'a [Value]) -> Result<Self, Error>

Returns a WhereClause given a list of clause components

pub fn matches_value(&self, value: &Value) -> bool

Evaluate this WhereClause against a provided Value

pub fn validate_array_element_clause( &self, document_type: DocumentTypeRef<'_>, platform_version: &PlatformVersion, ) -> Result<(), Error>

Judge a clause that names a typed array or reads its elements (protocol version 14): a typed array is read with contains or containsAny and nothing else, those two read a typed array, and each value they name must key as an element of the array’s element type. A value is judged the way a value of any other indexed property is, by whether it serializes as an index key of the type, so an identifier element may be given as its bytes or its base58 text. A clause on any other field passes.

pub fn validate_against_schema( &self, document_type: DocumentTypeRef<'_>, ) -> QuerySyntaxSimpleValidationResult

Validate this where clause against the document schema
