Enum jcm::MessageType

#[repr(u8)]
pub enum MessageType {
    Request(RequestType),
    Event(EventType),
    Reserved = 255,
}

Represents the message type.

Variants

Request(RequestType)

Host-to-device request message.

Event(EventType)

Device-to-host status event.

Reserved = 255

Reserved message type.

Implementations

impl MessageType

pub const fn new() -> Self

Creates a new MessageType.

pub const fn from_u8(val: u8) -> Self

Infallible conversion from a u8 into a RequestType.

pub const fn to_u8(&self) -> u8

Converts the MessageType to a u8.

pub const fn len() -> usize

Gets the length of the MessageType.

pub const fn request_type(&self) -> Result<RequestType>

Attempts to get the MessageType as a RequestType.

pub const fn event_type(&self) -> Result<EventType>

Attempts to get the MessageType as a EventType.

pub const fn is_request(&self) -> bool

pub const fn is_event(&self) -> bool

pub const fn is_empty(&self) -> bool

Gets whether the MessageType contains a reserved variant.

Trait Implementations

impl Clone for MessageType

fn clone(&self) -> MessageType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MessageType

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

Formats the value using the given formatter.

impl Default for MessageType

fn default() -> Self

Returns the “default value” for a type.

impl Display for MessageType

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

Formats the value using the given formatter.

impl From<&MessageType> for u8

fn from(val: &MessageType) -> Self

Converts to this type from the input type.

impl From<MessageType> for u8

fn from(val: MessageType) -> Self

Converts to this type from the input type.

impl PartialEq for MessageType

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<u8> for MessageType

type Error = Error

The type returned in the event of a conversion error.

fn try_from(val: u8) -> Result<Self>

Performs the conversion.

impl Copy for MessageType

impl Eq for MessageType

impl StructuralPartialEq for MessageType
