Enum boa::syntax::ast::op::UnaryOp

pub enum UnaryOp {
    IncrementPost,
    IncrementPre,
    DecrementPost,
    DecrementPre,
    Minus,
    Plus,
    Not,
}

A unary operation on a single value

Variants

IncrementPost

a++ - increment the value

IncrementPre

++a - increment the value

DecrementPost

a-- - decrement the value

DecrementPre

--a - decrement the value

Minus

-a - negate the value

Plus

+a - convert to a number

Not

!a - get the opposite of the boolean value

Trait Implementations

impl Clone for UnaryOp

fn clone(&self) -> UnaryOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnaryOp

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

Formats the value using the given formatter.

impl Display for UnaryOp

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

Formats the value using the given formatter.

impl Drop for UnaryOp

fn drop(&mut self)

Executes the destructor for this type.

impl Finalize for UnaryOp

fn finalize(&self)

impl PartialEq<UnaryOp> for UnaryOp

fn eq(&self, other: &UnaryOp) -> 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 !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Trace for UnaryOp

unsafe fn trace(&self)

Marks all contained Gcs.

unsafe fn root(&self)

Increments the root-count of all contained Gcs.

unsafe fn unroot(&self)

Decrements the root-count of all contained Gcs.

fn finalize_glue(&self)

Runs Finalize::finalize() on this object and all contained subobjects
