Implementations

impl UserDefinedOperator

pub const fn as_str(&self) -> &'static str

Returns the string representation of this type.

impl UserDefinedOperator

pub const fn args(&self) -> usize

Returns the number of arguments needed for this operator’s operation.

pub const fn is_unary(&self) -> bool

Returns whether self is a unary operator.

pub const fn is_binary(&self) -> bool

Returns whether self is a binary operator.

pub const fn is_bitwise(&self) -> bool

Returns whether self is a bitwise operator.

pub const fn is_arithmetic(&self) -> bool

Returns whether self is an arithmetic operator.

pub const fn is_comparison(&self) -> bool

Returns whether this is a comparison operator.

Trait Implementations

impl Clone for UserDefinedOperator

fn clone(&self) -> UserDefinedOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for UserDefinedOperator

impl Debug for UserDefinedOperator

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

Formats the value using the given formatter.

impl Display for UserDefinedOperator

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

Formats the value using the given formatter.

impl Eq for UserDefinedOperator

impl PartialEq for UserDefinedOperator

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