An enum of all the different kinds of wasm expressions.

Note that the #[walrus_expr] macro rewrites this enum's variants from

enum Expr {
    Variant { field: Ty, .. },
    ...
}

into

enum Expr {
    Variant(Variant),
    ...
}

struct Variant {
    field: Ty,
    ...
}

Variants

Block(Block)

A block of multiple expressions, and also a control frame.

Call(Call)

call

CallIndirect(CallIndirect)

call_indirect

LocalGet(LocalGet)

local.get n

LocalSet(LocalSet)

local.set n

LocalTee(LocalTee)

local.tee n

GlobalGet(GlobalGet)

global.get n

GlobalSet(GlobalSet)

global.set n

Const(Const)

*.const

Binop(Binop)

Binary operations, those requiring two operands

Unop(Unop)

Unary operations, those requiring one operand

Select(Select)

select

Unreachable(Unreachable)

unreachable

Br(Br)

br

BrIf(BrIf)

br_if

IfElse(IfElse)

if ... else ... end

BrTable(BrTable)

br_table

Drop(Drop)

drop

Return(Return)

return

MemorySize(MemorySize)

memory.size

MemoryGrow(MemoryGrow)

memory.grow

MemoryInit(MemoryInit)

memory.init

DataDrop(DataDrop)

data.drop

MemoryCopy(MemoryCopy)

memory.copy

MemoryFill(MemoryFill)

memory.fill

Load(Load)

Loading a value from memory

Store(Store)

Storing a value to memory

AtomicRmw(AtomicRmw)

An atomic read/modify/write operation

Cmpxchg(Cmpxchg)

An atomic compare exchange operation

AtomicNotify(AtomicNotify)

The atomic.notify instruction to wake up threads

AtomicWait(AtomicWait)

The *.atomic.wait instruction to block threads

WithSideEffects(WithSideEffects)

A value followed by one or more stack-neutral, side-effecting expressions.

This allows us to express "stacky" and "non-tree-like" expressions such as:

;; Assuming `f` has type `[] -> i32` and potential side effects.
call $f
call $f
call $f
drop
i32.add

Without WithSideEffects, we would need to create a synthetic block with a temporary local like this:

(i32.added
  (call $f)
  (block
    (set_local $temp (call $f))
    (drop (call $f))
    (get_local $temp)
  end))

But using WithoutSideEffects we can represent this like so:

(i32.add
  (with_side_effects
    ;; value
    (call $f)
    ;; side_effects
    (drop (call $f)))
  (call $f))

TableGet(TableGet)

TableSet(TableSet)
