Struct AndCondition

Source
pub struct AndCondition(pub Vec<Relation>);
Expand description

An incomplete AST representation of a plural rule. Comprises a vector of Relations.

🚧 This code is considered unstable; it may change at any time, in breaking or non-breaking ways, including in SemVer minor releases. In particular, the `DataProvider` implementations are only guaranteed to match with this version's `*_unstable` providers. Use with caution.

§Examples

All AST nodes can be built explicitly, as seen in the example. However, due to its complexity, it is preferred to build the AST using the parse() function.

"i = 3 and v = 0"

Can be represented by the AST:

use icu::plurals::provider::rules::reference::ast::*;

AndCondition(vec![
    Relation {
        expression: Expression {
            operand: Operand::I,
            modulus: None,
        },
        operator: Operator::Eq,
        range_list: RangeList(vec![RangeListItem::Value(Value(5))]),
    },
    Relation {
        expression: Expression {
            operand: Operand::V,
            modulus: None,
        },
        operator: Operator::NotEq,
        range_list: RangeList(vec![RangeListItem::Value(Value(2))]),
    },
]);
