Enum UpdateDeadline

#[non_exhaustive]
pub enum UpdateDeadline {
    Interrupt,
    Continue(u64),
    Yield(u64),
    YieldCustom(u64, Pin<Box<dyn Future<Output = ()> + Send>>),
}

Available on crate feature runtime only.

What to do after returning from a callback when the engine epoch reaches the deadline for a Store during execution of a function using that store.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Interrupt

Halt execution of WebAssembly, don’t update the epoch deadline, and raise a trap.

Continue(u64)

Extend the deadline by the specified number of ticks.

Yield(u64)

Available on crate feature async only.

Extend the deadline by the specified number of ticks after yielding to the async executor loop. This can only be used with an async Store configured via Config::async_support.

YieldCustom(u64, Pin<Box<dyn Future<Output = ()> + Send>>)

Available on crate feature async only.

Extend the deadline by the specified number of ticks after yielding to the async executor loop. This can only be used with an async Store configured via Config::async_support.

The yield will be performed by the future provided; when using tokio it is recommended to provide tokio::task::yield_now here.
