}

Implementations

impl Predicate

pub fn eq(field: impl Into<String>, value: FieldValue) -> Self

pub fn gt(field: impl Into<String>, value: FieldValue) -> Self

pub fn gte(field: impl Into<String>, value: FieldValue) -> Self

pub fn lt(field: impl Into<String>, value: FieldValue) -> Self

pub fn lte(field: impl Into<String>, value: FieldValue) -> Self

pub fn prefix(field: impl Into<String>, prefix: impl Into<Bytes>) -> Self

pub fn in_values(field: impl Into<String>, values: Vec<FieldValue>) -> Self

pub fn is_not_null(field: impl Into<String>) -> Self

impl Predicate

pub fn evaluate(&self, value: &FieldValue) -> bool

Evaluate this predicate against a record field value. Returns true if the record satisfies the predicate.

Trait Implementations

impl Clone for Predicate

fn clone(&self) -> Predicate
