Enum fidl_examples_keyvaluestore_supportexports::StoreRequest

pub enum StoreRequest {
    WriteItem {
        attempt: Item,
        responder: StoreWriteItemResponder,
    },
    Export {
        empty: Vmo,

}

A very basic key-value store - so basic, in fact, that one may only write to it, never read!

Variants

WriteItem

Writes an item to the store.

Fields

attempt: Item

responder: StoreWriteItemResponder

Export

Exports the entire store as a persistent Exportable FIDL object into a VMO provided by the client.

By having the client provide (and speculatively size) the VMO, we force the party requesting the relatively heavy load of generating a backup to acknowledge and bear some of the costs.

This method operates by having the client supply an empty VMO, which the server then attempts to fill. Notice that the server removes the zx.Rights.WRITE and zx.Rights.SET_PROPERTY rights from the returned VMO - not even the requesting client may alter the backup once it has been minted by the server.

Fields

empty: Vmo

responder: StoreExportResponder

_UnknownMethod

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

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

method_type: MethodType
