Enum Fixity 

pub enum Fixity {
    Prefix,
    InfixLeft,
    InfixRight,
    Postfix,
    Mixfix,
}

The grammatical position an operator occupies relative to its operands.

Variants

Prefix

Operator precedes its single operand (for example, unary minus).

InfixLeft

Left-associative infix operator between two operands.

InfixRight

Right-associative infix operator between two operands.

Postfix

Operator follows its single operand (for example, a factorial mark).

Mixfix

Operator with operands interleaved among multiple fixed parts.

Trait Implementations

impl Clone for Fixity

fn clone(&self) -> Fixity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Fixity

impl Debug for Fixity

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

Formats the value using the given formatter.

impl Eq for Fixity

impl Ord for Fixity

fn cmp(&self, other: &Fixity) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Fixity

fn eq(&self, other: &Fixity) -> 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 Fixity

fn partial_cmp(&self, other: &Fixity) -> 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.
