Struct Operator

pub struct Operator<O> {
    pub op: O,
    pub associativity: Associativity,
    pub size: OperatorSize,
    pub precedence: usize,
    pub parser: Box<dyn Fn(&[u8]) -> IResult<&[u8], &[u8]>>,
}

An Operator wrapper with extra info for parsing

Fields

op: O

The underlying operator enum

associativity: Associativity

The associativity of the operator

size: OperatorSize

Size of the operator, Unary, Binary, etc…

precedence: usize

The precedence of the operator If * has precedence 10 and - has precedence 9 the following expression 1 * 2 - 3 would parse as (1 * 2) - 3

parser: Box<dyn Fn(&[u8]) -> IResult<&[u8], &[u8]>>

The nom parser function

Implementations

impl<O> Operator<O>

pub fn new( op: O, assoc: Associativity, size: OperatorSize, prec: usize, parser: Box<dyn Fn(&[u8]) -> IResult<&[u8], &[u8]>>, ) -> Self

Creates a new operator

Trait Implementations

impl<O: Debug> Debug for Operator<O>

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

Formats the value using the given formatter.

impl<O: PartialEq> PartialEq for Operator<O>

fn eq(&self, other: &Operator<O>) -> 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.
