Enum rusymbols::core::Actions

pub enum Actions {
    Sub,
    Add,
    Mul,
    Div,
    Pow,
    Var(String),
    Val(f64),
    Brackets(Box<Expression>, Brackets),
}

Available math actions and service information.

These “actions” can be compared with each other to determine priority. The higher the priority, the earlier the value will be calculated.

Variants

Sub

subtraction “-”

Add

addition “+”

Mul

multiplication “*”

Div

division “/”

Pow

exponentiation “**”

Var(String)

Not really an action - it’s a variable literal

Val(f64)

It’s also not really an action - it’s just a value or a number.

Brackets(Box<Expression>, Brackets)

Expression in parentheses. Brackets also shows the shape of the brackets.

Trait Implementations

impl Clone for Actions

fn clone(&self) -> Actions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Actions

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

Formats the value using the given formatter.

impl Default for Actions

fn default() -> Self

Returns the “default value” for a type.

impl Display for Actions

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

Formats the value using the given formatter.

impl PartialEq<Actions> for Actions

These “actions” can be compared with each other to determine priority. The higher the priority, the earlier the value will be calculated.

Examples

use rusymbols::core::Actions;
assert_eq!(Actions::Add, Actions::Sub); // Subtraction and addition have equal priority.
assert_ne!(Actions::Add, Actions::Mul); // Addition and multiplication have different priorities.

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

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

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<Actions> for Actions

These “actions” can be compared with each other to determine priority. The higher the priority, the earlier the value will be calculated.

#Example:

use rusymbols::core::Actions;
assert!(Actions::Add < Actions::Mul); // Subtraction and addition have equal priority.
assert!(Actions::Mul < Actions::Pow); // Addition and multiplication have different priorities.

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

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

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

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

#[must_use]pub fn le(&self, other: &Rhs) -> bool

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

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

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

#[must_use]pub fn ge(&self, other: &Rhs) -> bool

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