Struct Crc16

#[repr(C)]
pub struct Crc16(/* private fields */);

Represents the 16-bit CRC used to protect SD memory card commands, responses, and data transfer messages.

Implementations

impl Crc16

pub const fn new() -> Self

Creates a new Crc16.

pub const fn bits(&self) -> u16

Gets the inner representation of the Crc16 bits.

pub const fn calculate(buf: &[u8]) -> Self

Calculates the CRC7 value according the algorithm defined in the simplified physical specification. See section “4.5 Cyclic Redundancy Code” for details.

Generator Polynomial: G(x) = x^16 + x^12 + x^5 + 1
M(x) = (first bit) * x^n + (second bit) * x^n-1 + ... + (last bit) * x^0
CRC[15..0] = Remainder[(M(x) * x^16) / G(x)]

Trait Implementations

impl Clone for Crc16

fn clone(&self) -> Crc16

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Crc16

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

Formats the value using the given formatter.

impl Default for Crc16

fn default() -> Self

Returns the “default value” for a type.

impl From<Crc16> for u16

fn from(val: Crc16) -> Self

Converts to this type from the input type.

impl From<u16> for Crc16

fn from(val: u16) -> Self

Converts to this type from the input type.

impl PartialEq for Crc16

fn eq(&self, other: &Crc16) -> 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.
