Struct Div4 

pub struct Div4(/* private fields */);

This type represents a divider in the range 1..=16.

At a hardware level, this is an 8-bit register from 0..=15, which adds one.

While the clock domain seems to use 8-bit dividers, the peripheral domain seems to use 4 bit dividers!

Implementations

impl Div4

pub const fn no_div() -> Self

Divide by one, or no division

pub const fn from_raw(n: u8) -> Option<Self>

Store a “raw” divisor value that will divide the source by (n + 1), e.g. Div4::from_raw(0) will divide the source by 1, and Div4::from_raw(15) will divide the source by 16.

pub const fn from_divisor(n: u8) -> Option<Self>

Store a specific divisor value that will divide the source by n. e.g. Div4::from_divisor(1) will divide the source by 1, and Div4::from_divisor(16) will divide the source by 16.

Will return None if n is not in the range 1..=16. Consider Self::from_raw for an infallible version.

pub const fn into_bits(self) -> u8

Convert into “raw” bits form

pub const fn into_divisor(self) -> u32

Convert into “divisor” form, as a u32 for convenient frequency math

Trait Implementations

impl Clone for Div4

fn clone(&self) -> Div4

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Div4

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

Formats the value using the given formatter.

impl PartialEq for Div4

fn eq(&self, other: &Div4) -> 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.
