Struct DeviceMessage

#[non_exhaustive]
pub struct DeviceMessage {
    pub contents: Option<Contents>,
    /* private fields */
}

A message returned from a device.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

contents: Option<Contents>

Implementations

impl DeviceMessage

pub fn new() -> Self

pub fn set_contents<T: Into<Option<Contents>>>(self, v: T) -> Self

Sets the value of contents.

Note that all the setters affecting contents are mutually exclusive.

pub fn status_update(&self) -> Option<&Box<StatusUpdate>>

The value of contents if it holds a StatusUpdate, None if the field is not set or holds a different branch.

pub fn set_status_update<T: Into<Box<StatusUpdate>>>(self, v: T) -> Self

Sets the value of contents to hold a StatusUpdate.

Note that all the setters affecting contents are mutually exclusive.

pub fn stream_status(&self) -> Option<&Box<StreamStatus>>

The value of contents if it holds a StreamStatus, None if the field is not set or holds a different branch.

pub fn set_stream_status<T: Into<Box<StreamStatus>>>(self, v: T) -> Self

Sets the value of contents to hold a StreamStatus.

Note that all the setters affecting contents are mutually exclusive.

pub fn stream_data(&self) -> Option<&Box<StreamData>>

The value of contents if it holds a StreamData, None if the field is not set or holds a different branch.

pub fn set_stream_data<T: Into<Box<StreamData>>>(self, v: T) -> Self

Sets the value of contents to hold a StreamData.

Note that all the setters affecting contents are mutually exclusive.

Trait Implementations

impl Clone for DeviceMessage

fn clone(&self) -> DeviceMessage

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceMessage

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

Formats the value using the given formatter.

impl Default for DeviceMessage

fn default() -> DeviceMessage

Returns the “default value” for a type.

impl Message for DeviceMessage

fn typename() -> &'static str

The typename of this message.

impl PartialEq for DeviceMessage

fn eq(&self, other: &DeviceMessage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
