Struct Condition

pub struct Condition(pub Vec<AndCondition>);

A complete AST representation of a plural rule’s condition. Comprises a vector of AndConditions.

🚧 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

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

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

    condition,
    parse_condition(b"i = 5 or v = 2").expect("Parsing failed")

Trait Implementations

impl Clone for Condition

fn clone(&self) -> Condition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Condition

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

Formats the value using the given formatter.

impl PartialEq for Condition

fn eq(&self, other: &Condition) -> 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.
