Enum erdnuss_comms::CmdAddr

pub enum CmdAddr {

}

Command + Address byte

CmdAddr is a combined Command and Address byte. It consists of:

• 3 command-bits (0..=7)
• 5 address-bits (0..=31)

The command bits are most significant, and the address bits are least significant, e.g. 0bCCC_AAAAA, where C are command bits and A are address bits.

The address bits are the logical address of the target, which may be a source or destination, depending on the message kind.

Commands 1, 2, 4, 5, and 7 are assigned as described below. Commands 0, 3, and 6 are reserved for future use, and currently considered invalid.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SelectAddr(u8)

Select - 0b001

Used when the Controller is addressing a Target.

ReplyFromAddr(u8)

Reply - 0b010

Used when the Target is responding to the Controller.

DiscoveryOffer(u8)

Discovery Offer - 0b100

Used when the Controller is offering an unused logical address to Targets without one. The offered address is the one in the 5-bit address field.

DiscoveryClaim(u8)

Discovery Claim - 0b0101

Used when a Target attempts to claim a Discovery Offer message.

DiscoverySuccess(u8)

Discovery Success - 0b111

used when the Controller is informing a Target that its address claim is (tentatively) successful. The Target must respond to this message with an empty Reply.

Trait Implementations

impl Debug for CmdAddr

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

Formats the value using the given formatter.

impl From<CmdAddr> for u8

fn from(val: CmdAddr) -> Self

Converts to this type from the input type.

impl PartialEq for CmdAddr

fn eq(&self, other: &CmdAddr) -> 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 CmdAddr

type Error = CmdAddrError

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for CmdAddr
