Enum CounterRequest

pub enum CounterRequest {
    Increment {
        responder: CounterIncrementResponder,
    },
    ConnectToProtocol {
        protocol_name: String,
        request: Channel,

    },
    TryOpenDirectory {
        path: String,
        responder: CounterTryOpenDirectoryResponder,
    },
}

Sample interface that keeps a stateful integer counter starting at zero.

Variants

Increment

Increments internal counter by one and returns new counter value.

Fields

responder: CounterIncrementResponder

ConnectToProtocol

Connects request to a protocol in the /svc directory named protocol_name.

Fields

protocol_name: String

request: Channel

control_handle: CounterControlHandle

OpenInNamespace

Opens the node found at path in the component’s namespace with flags, and connects request.

This is essentially a wrapper around [fuchsia.io/Directory.Open], which always opens in an implementation-defined mode.

• request path the absolute path from the root of the server’s namespace.
• request flags the rights with which to open the node.
• request request the server end channel to the node.

Fields

path: String

flags: Flags

request: Channel

control_handle: CounterControlHandle

TryOpenDirectory

Opens the directory found at path.

• request path the absolute path from the server’s namespace.

• error ZX_ERR_NOT_FOUND if the directory at path is not in the server’s namespace.
• error ZX_ERR_IO if there is some other unspecified error during I/O.

Fields

path: String

responder: CounterTryOpenDirectoryResponder
