Struct icu_plurals::rules::ast::AndCondition

pub struct AndCondition(pub Box<[Relation]>);

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

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::rules::ast::*;

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

Trait Implementations

impl Clone for AndCondition

fn clone(&self) -> AndCondition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AndCondition

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

Formats the value using the given formatter.

impl PartialEq<AndCondition> for AndCondition

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

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

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

This method tests for !=.
