Struct Request 

pub struct Request<Op>
where
    Op: Operation,
{
    pub operation: Op,
    pub handle: RequestHandle<Op::Output>,
}

Request represents an effect request from the core to the shell.

The operation is the input needed to process the effect, and will be one of the capabilities’ Operation types.

The request can be resolved by passing it to Core::resolve along with the corresponding result of type Operation::Output.

Fields

operation: Op

handle: RequestHandle<Op::Output>

Implementations

impl<Op> Request<Op>

where Op: Operation, Op::Output: for<'de> Deserialize<'de>,

pub fn serialize<F, Eff, T>(self, effect: F) -> (Eff, ResolveSerialized<T>)

where F: FnOnce(Op) -> Eff, T: FfiFormat,

Serialize this effect request using effect as a constructor for a serializable Effect Eff

You should never need to call this method yourself, it will be called by the generated implementation of Effect::serialize, which is used by the Bridge implementation.

impl<Op> Request<Op>

where Op: Operation,

pub fn resolve(&mut self, output: Op::Output) -> Result<(), ResolveError>

Resolve the request with the given output.

Errors

Returns an error if the request does not expect to be resolved.

pub fn split(self) -> (Op, RequestHandle<Op::Output>)

Trait Implementations

impl<Op> Debug for Request<Op>

where Op: Operation + Debug,

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

Formats the value using the given formatter.

impl<Op> Resolvable<<Op as Operation>::Output> for Request<Op>

where Op: Operation,

fn resolve(&mut self, output: Op::Output) -> Result<(), ResolveError>

Resolve the request with the given output.

Note: This method should only be used in tests that work directly with Command. If you are using AppTester to test your app, you should use AppTester::resolve instead.

Errors

Errors if the request cannot (or should not) be resolved.
