Struct icu::plurals::rules::ast::Condition

pub struct Condition(pub Box<[AndCondition], Global>);

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

Examples

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

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

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

Trait Implementations

impl Clone for Condition

pub fn clone(&self) -> Condition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Condition

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

Formats the value using the given formatter.

impl PartialEq<Condition> for Condition

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

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &Condition) -> bool

This method tests for !=.
