Struct TSL31Packet 

pub struct TSL31Packet<T: AsRef<[u8]>> { /* private fields */ }

A wrapper around a byte slice reference representing a TSL v3.1 Packet

Implementations

impl<T> TSL31Packet<T>

where T: AsRef<[u8]>,

pub fn new_unchecked(buf: T) -> Self

Summon a packet from the given bytes without checking it.

pub fn new_checked(buf: T) -> Result<Self, Error>

Validate the the given bytes are a packet and return it, or an error

pub fn inner(self) -> T

Consumes self, returning the inner bytes

pub fn display_data(&self) -> &str

Return the display data as a string, with trailing space/null bytes removed

pub fn address(&self) -> u8

The packet address, from 0x00..=0x7E

pub fn tally(&self) -> [bool; 4]

Tally states, 4 channels

pub fn brightness(&self) -> Brightness

Tally brightness

impl<T> TSL31Packet<T>

where T: AsMut<[u8]> + AsRef<[u8]>,

pub fn set_address(&mut self, addr: u8) -> Result<(), ()>

Set the address. Return Err(()) if the addr is out of range

pub fn set_tally(&mut self, state: [bool; 4])

Set the tally state

pub fn set_brightness(&mut self, brightness: Brightness)

pub fn set_display_data<'a, S>(&mut self, s: S)

where S: Into<&'a str>,

Set the display data. Panics if length > 16 or string does not contain printable ascii

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

Formats the value using the given formatter.

impl<T> Display for TSL31Packet<T>

where T: AsRef<[u8]>,

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

Formats the value using the given formatter.

impl<T: PartialEq + AsRef<[u8]>> PartialEq for TSL31Packet<T>

fn eq(&self, other: &TSL31Packet<T>) -> 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.
