Struct IndexPredicateExpression 

pub struct IndexPredicateExpression {
    pub expression: Option<Expression>,
}

One bounded Boolean predicate expression. Leaves retain their declared field capability checks. Conjunction and disjunction require at least one child; negation requires exactly one child. Servers reject expressions deeper than 32 levels or containing more than 256 total nodes.

Fields

expression: Option<Expression>

Implementations

impl IndexPredicateExpression

pub fn leaf(predicate: IndexPredicate) -> Self

Construct one leaf expression.

pub fn all( expressions: impl IntoIterator<Item = Self>, ) -> Result<Self, PredicateExpressionError>

Construct a non-empty conjunction.

pub fn any( expressions: impl IntoIterator<Item = Self>, ) -> Result<Self, PredicateExpressionError>

Construct a non-empty disjunction.

pub fn negated(self) -> Self

Negate this complete expression.

Trait Implementations

impl Clone for IndexPredicateExpression
