Enum UnOp

pub enum UnOp {
    Pos,
    Neg,
    Not,
}

A unary operator.

Variants

Pos

The plus operator: +.

Neg

The negation operator: -.

Not

The boolean not.

Implementations

impl UnOp

pub fn from_kind(token: SyntaxKind) -> Option<Self>

Try to convert the token into a unary operation.

pub fn precedence(self) -> usize

The precedence of this operator.

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

The string representation of this operation.

Trait Implementations

impl Clone for UnOp

fn clone(&self) -> UnOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnOp

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

Formats the value using the given formatter.

impl Hash for UnOp

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for UnOp

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