Kinds of metamethods that can be overridden.

Currently, this mechanism does not allow overriding the __gc metamethod, since there is generally no need to do so: UserData implementors can instead just implement Drop.

Variants

Add

The + operator.

Sub

The - operator.

Mul

The * operator.

Div

The / operator.

Mod

The % operator.

Pow

The ^ operator.

Unm

The unary minus (-) operator.

IDiv

The floor division (//) operator.

BAnd

The bitwise AND (&) operator.

BOr

The bitwise OR (|) operator.

BXor

The bitwise XOR (binary ~) operator.

BNot

The bitwise NOT (unary ~) operator.

Shl

The bitwise left shift (<<) operator.

Shr

The bitwise right shift (>>) operator.

Concat

The string concatenation operator ...

Len

The length operator #.

Eq

The == operator.

Lt

The < operator.

Le

The <= operator.

Index

Index access obj[key].

NewIndex

Index write access obj[key] = value.

Call

The call “operator” obj(arg1, args2, ...).

ToString

The __tostring metamethod.

This is not an operator, but will be called by methods such as tostring and print.

Pairs

The __pairs metamethod.

This is not an operator, but it will be called by the built-in pairs function.

Trait Implementations

impl Clone for MetaMethod

fn clone(&self) -> MetaMethod

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetaMethod

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

Formats the value using the given formatter.

impl Hash for MetaMethod

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<MetaMethod> for MetaMethod

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

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

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

This method tests for !=.
