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_against_schema( &self, document_type: DocumentTypeRef<'_>, ) -> QuerySyntaxSimpleValidationResult

Validate this where clause against the document schema

Trait Implementations

impl Clone for WhereClause

fn clone(&self) -> WhereClause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WhereClause

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WhereClause

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<WhereClause> for Value

fn from(value: WhereClause) -> Self

Converts to this type from the input type.

impl PartialEq for WhereClause

fn eq(&self, other: &WhereClause) -> 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 WhereClause

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
