Struct ReadResponse 

pub struct ReadResponse { /* private fields */ }

Read response datagram (8 bytes).

Format: [SYNC, master_addr (0xFF), reg_addr, data[3], data[2], data[1], data[0], CRC]

Implementations

impl ReadResponse

pub const LEN: usize = 8

Length of a read response in bytes.

pub const SYNC_IDX: usize = 0

Index of the sync byte.

pub const MASTER_ADDR_IDX: usize = 1

Index of the master address byte.

pub const REG_ADDR_IDX: usize = 2

Index of the register address byte.

pub const DATA_START_IDX: usize = 3

Start index of data bytes.

pub const DATA_END_IDX: usize = 7

End index of data bytes (exclusive).

pub const CRC_IDX: usize = 7

Index of the CRC byte.

pub fn from_bytes<E>(bytes: [u8; 8]) -> Result<Self, Error<E>>

Parse a read response from a byte buffer.

Arguments

• bytes - 8-byte buffer containing the response

Returns

The parsed response, or an error if validation fails.

pub fn from_slice<E>(slice: &[u8]) -> Result<Self, Error<E>>

Parse a response from a slice, copying the data.

Errors

Returns Error::BufferTooSmall if the slice is less than 8 bytes.

pub fn reg_addr(&self) -> u8

Get the register address from the response.

pub fn address(&self) -> Option<Address>

Get the typed register address if known.

pub fn data(&self) -> u32

Get the 32-bit data value.

pub fn as_bytes(&self) -> &[u8; 8]

Get the raw bytes of the response.

pub fn crc_valid(&self) -> bool

Check if the CRC is valid.

Trait Implementations

impl AsRef<[u8]> for ReadResponse

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

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

impl Clone for ReadResponse

fn clone(&self) -> ReadResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReadResponse

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

Formats the value using the given formatter.

impl Format for ReadResponse

where [u8; 8]: Format,

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

Writes the defmt representation of self to fmt.

impl PartialEq for ReadResponse

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