Enum Command 

pub enum Command {
    GetVersion,
    ListDevices,
    GetWatchPolicy,
    SetWatchPolicy(Watch),
    Poll,
    GetDevice,
    SetDevice(Device),
}

Commands that can be sent to the gpsd server.

Variants

GetVersion

Gets the version of the gpsd server.

The server will respond with a Version object.

ListDevices

Lists all devices that gpsd knows about.

The server will respond with a Devices object.

GetWatchPolicy

Gets the current watch policy.

The server will respond with a Watch object.

SetWatchPolicy(Watch)

Sets the watch policy.

The server will respond with a Devices object followed by a Watch object.

Poll

Requests data from the last-seen fixes on all active GPS devices.

Devices must previously have their watch policy set to enabled to be pollable.

The server will respond with a Poll object.

GetDevice

Reports the state of a device.

The server will respond with a Device object.

SetDevice(Device)

Sets device-specific control bits.

The server will respond with a Device object.

Implementations

impl Command

pub fn set_watch_policy() -> SetWatchPolicyBuilder

Creates a new builder for the command.

Trait Implementations

impl Debug for Command

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

Formats the value using the given formatter.

impl Encoder<Command> for ObjectCodec

type Error = Error

The type of encoding errors.

fn encode( &mut self, item: Command, dst: &mut BytesMut, ) -> Result<(), Self::Error>

Encodes a frame into the buffer provided.

impl Sink<Command> for Channel

type Error = Error

The type of value produced by the sink when an error occurs.

fn poll_ready( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, item: Command) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output and close this sink, if necessary.
