Enum fidl_examples_keyvaluestore_usegenericvalues::StoreRequest

pub enum StoreRequest {
    WriteItem {
        payload: StoreWriteItemRequest,
        responder: StoreWriteItemResponder,
    },
    _UnknownMethod {
        ordinal: u64,

}

A very basic key-value store.

Variants

WriteItem

Fields

payload: StoreWriteItemRequest

responder: StoreWriteItemResponder

Writes an item to the store.

Since the value stored in the key-value store can now be different from the input (if the WriteOptions.CONCAT flag is set), we need to return the resulting Value to the requester.

We use an (anonymous) table and a (named) flexible union as the request and response payload, respectively, to allow for easier future evolution. Both of these types are flexible, meaning that adding or removing members is binary-compatible. This makes them much easier to evolve that the struct types that were previously used, which cannot be changed after release without breaking ABI.

_UnknownMethod

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: StoreControlHandle

unknown_method_type: UnknownMethodType

An interaction was received which does not match any known method.
