Enum AssignOp

pub enum AssignOp {
    Let,
    Set,
    Op(Op),
}

An assignment operator, e.g. the += in x += 1;.

Variants

Let

x = 1 declares the name x and initialises it to 1.

Set

x := 1 overwrites the value of the name x with 1.

Op(Op)

x += 1 is an abbreviation for x := x + 1.

Trait Implementations

impl Clone for AssignOp

fn clone(&self) -> AssignOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AssignOp

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

Formats the value using the given formatter.

impl PartialEq for AssignOp

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

impl Tree for AssignOp

fn declare_keywords(declare: impl FnMut(&'static str, Self))

declare() all the keywords whose parse trees are Selfs.

impl Copy for AssignOp

impl StructuralPartialEq for AssignOp
