class CoroutineSuspendExpr

Declaration

class CoroutineSuspendExpr : public Expr { /* full declaration omitted */ };

Description

Represents an expression that might suspend coroutine execution; either a co_await or co_yield expression. Evaluation of this expression first evaluates its 'ready' expression. If that returns 'false': -- execution of the coroutine is suspended -- the 'suspend' expression is evaluated -- if the 'suspend' expression returns 'false', the coroutine is resumed -- otherwise, control passes back to the resumer. If the coroutine is not suspended, or when it is resumed, the 'resume' expression is evaluated, and its result is the result of the overall expression.
