Implementations

impl WordSize

pub const LARGEST: WordSize = WordSize::FourBytes

Largest WordSize supported by this HAL driver.

pub const fn bytes(self) -> usize

Size in bytes.

pub const fn to_hw_size(self) -> Size

Convert to hardware SSIZE/DSIZE field value.

pub const fn from_bytes(bytes: u8) -> Option<Self>

Create from byte width (1, 2, or 4).

Trait Implementations

impl Clone for WordSize

fn clone(&self) -> WordSize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WordSize

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

Formats the value using the given formatter.

impl Default for WordSize

fn default() -> WordSize

Returns the “default value” for a type.

impl Format for WordSize

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

Writes the defmt representation of self to fmt.

impl PartialEq for WordSize

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