Struct Datagram

pub struct Datagram { /* private fields */ }

Representation of a datagram

The total length is limited to 128 bits The bits of a telegram are internally enumerated from 0 to 127. A default datagram is expected to be empty (i.e. containing zero bits)

Implementations

impl Datagram

pub fn len(&self) -> u8

pub fn is_empty(&self) -> bool

pub fn extract_data(&self, min: u8, max: u8) -> u128

Extract a data slice from the datagram

Args

• min - start index (included)
• max - max index (not included)

Returns

the extracted value

Panics

if 0 <= min < max <= len() is violated

Example

use manchester_code::Datagram;

let datagram = Datagram::new("0-111_10101_00001111");
assert_eq!(0b1111, datagram.extract_data(0, 4));
assert_eq!(0b1111, datagram.extract_data(0, 8));
assert_eq!(0b1111, datagram.extract_data(datagram.len()-5, datagram.len()));

pub fn new(bit_repr: &str) -> Self

Create a new datagram from “binary” string

Arguments

• bit_repr - Bit representation as string of zeros and ones. Arbitrary delimiter signs (for readability) are ignored

Example

use manchester_code::Datagram;

let datagram = Datagram::new("0-111_10101_00001111");

Trait Implementations

impl Clone for Datagram

fn clone(&self) -> Datagram

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Datagram

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

Formats the value using the given formatter.

impl Default for Datagram

fn default() -> Datagram

Returns the “default value” for a type.

impl Format for Datagram

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

Writes the defmt representation of self to fmt.

impl Index<u8> for Datagram

fn index(&self, index: u8) -> &Self::Output

Access the n-th element via index

Panics

• if the index is out of range

Example

use manchester_code::Datagram;

let datagram = Datagram::new("0-111_10101_00001111");
assert_eq!(1, datagram[0]);
assert_eq!(0, datagram[5]);

type Output = u128

The returned type after indexing.

impl PartialEq for Datagram

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

impl Copy for Datagram
