Struct icu_plurals::rules::ast::Expression

pub struct Expression {
    pub operand: Operand,
    pub modulus: Option<Value>,
}

An incomplete AST representation of a plural rule. Comprises an Operand and an optional modulo.

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 % 100"

Can be represented by the AST:

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

Expression {
    operand: Operand::I,
    modulus: Some(Value(100)),
};

Fields

operand: Operand

modulus: Option<Value>

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl PartialEq<Expression> for Expression

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

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

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

This method tests for !=.
