Struct AndCondition

pub struct AndCondition(pub Vec<Relation>);

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))]),
    },
]);

Trait Implementations

impl Clone for AndCondition

fn clone(&self) -> AndCondition

Returns a copy of the value.

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 for AndCondition

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