Slot Details

compareAndSet

Bool compareAndSet(Bool expect, Bool update)

Atomically set the value to update if current value is equivalent to the expect value. Return true if updated, or false if current value was not equal to the expected value.

getAndSet

Bool getAndSet(Bool val)

Atomically set the value and return the previous value.

make

new make(Bool val := false)

Construct with initial value

toStr

virtual override Str toStr()

Return val.toStr

val

Bool val

The current boolean value
