Struct exmex::BinOp

pub struct BinOp<T: Clone> {
    pub apply: fn(_: T, _: T) -> T,
    pub prio: i64,
    pub is_commutative: bool,
}

A binary operator that consists of a function pointer, a priority, and a commutativity-flag.

Fields

apply: fn(_: T, _: T) -> T

Implementation of the binary operation, e.g., |a, b| a * b for multiplication.

prio: i64

Priority of the binary operation. A binary operation with a higher number will be executed first. For instance, in a sane world * has a higher priority than +. However, in Exmex land you could also define this differently.

is_commutative: bool

True if this is a commutative operator such as * or +, false if not such as -, /, or ^. Commutativity is used to compile sub-expressions of numbers correctly.

Trait Implementations

impl<T: Clone + Clone> Clone for BinOp<T>

fn clone(&self) -> BinOp<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Clone> Debug for BinOp<T>

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

Formats the value using the given formatter.

impl<T: Ord + Clone> Ord for BinOp<T>

fn cmp(&self, other: &BinOp<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

impl<T: PartialEq + Clone> PartialEq<BinOp<T>> for BinOp<T>

fn eq(&self, other: &BinOp<T>) -> bool

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

fn ne(&self, other: &BinOp<T>) -> bool

This method tests for !=.

impl<T: PartialOrd + Clone> PartialOrd<BinOp<T>> for BinOp<T>

fn partial_cmp(&self, other: &BinOp<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
