Expand description

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.

impl PartialEq<MetaMethod> for MetaMethod

source§

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

1.0.0 · source§

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
