Struct OperatorInfo 

pub struct OperatorInfo {
    pub precedence: Precedence,
    pub associativity: Associativity,
}

Operator information containing precedence and associativity.

This structure encapsulates the essential properties needed for operator precedence parsing, including the precedence level and how operators of the same precedence should be grouped.

Fields

precedence: Precedence

The precedence level of the operator (higher values have higher precedence)

associativity: Associativity

The associativity of the operator (Left, Right, or None)

Implementations

impl OperatorInfo

pub fn new(precedence: Precedence, associativity: Associativity) -> Self

Creates a new operator with the specified precedence and associativity.

Arguments

• precedence - The precedence level of the operator (higher values have higher precedence)
• associativity - The associativity of the operator (Left, Right, or None)

Examples

let op = OperatorInfo::new(10, Associativity::Left);

pub fn left(precedence: Precedence) -> Self

Creates a left-associative operator with the specified precedence.

Arguments

• precedence - The precedence level of the operator

Examples

let left_op = OperatorInfo::left(5);

pub fn right(precedence: Precedence) -> Self

Creates a right-associative operator with the specified precedence.

Arguments

• precedence - The precedence level of the operator

Examples

let right_op = OperatorInfo::right(8);

pub fn none(precedence: Precedence) -> Self

Creates a non-associative operator with the specified precedence.

Arguments

• precedence - The precedence level of the operator

Examples

let non_assoc_op = OperatorInfo::none(3);
