Variants

Lowest

The lowest value precedence

Equals

Equality comparison operator ==

LessGreater

Strictly greater/less than operators > or <

Sum

Summation operator +

Product

Multiplication operator *

Prefix

Prefix operators, e.g., -X or !X

Call

Function calls, e.g., myFunction(X)

Index

Index access, e.g., myArray[i]

Trait Implementations

impl Debug for Precdence

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

Formats the value using the given formatter.

impl PartialEq for Precdence

fn eq(&self, other: &Precdence) -> 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.

impl PartialOrd for Precdence

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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