Struct ReadRequest 

pub struct ReadRequest { /* private fields */ }

Read request datagram (4 bytes).

Format: [SYNC, slave_addr, reg_addr, CRC]

Implementations

impl ReadRequest

pub const LEN: usize = 4

Length of a read request in bytes.

pub fn new(slave_addr: u8, reg_addr: Address) -> Self

Create a new read request for the given slave and register address.

Arguments

• slave_addr - Slave address (0-3)
• reg_addr - Register address to read

pub fn from_raw_addr(slave_addr: u8, reg_addr: u8) -> Self

Create a read request from a raw register address.

Use this when you need to read a register by its raw address value.

pub fn as_bytes(&self) -> &[u8]

Get the request as a byte slice.

pub fn slave_addr(&self) -> u8

Get the slave address.

pub fn reg_addr(&self) -> u8

Get the register address.

Trait Implementations

impl AsRef<[u8]> for ReadRequest

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ReadRequest

fn clone(&self) -> ReadRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReadRequest

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

Formats the value using the given formatter.

impl Format for ReadRequest

where [u8; 4]: Format,

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl PartialEq for ReadRequest

fn eq(&self, other: &ReadRequest) -> 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.
