Struct RotaryEncoderEvent 

pub struct RotaryEncoderEvent { /* private fields */ }

Event generated by the process() function.

Implementations

impl RotaryEncoderEvent

pub fn value(&self) -> i32

Returns the current value.

pub fn direction(&self) -> Direction

Returns the direction of movement.

pub fn step(&self) -> i32

Returns the step value. +1 for clockwise, -1 for counter-clockwise.

pub fn timedelta(&self) -> Option<u64>

Returns optional time units since last event.

pub fn velocity(&self, update_freq: i32) -> Option<i32>

Returns the optional velocity in respect of the timebase. E.g. if process() is called in 1ms intervall, the timebase is 1000. Calling this function with that value will return the number of events per second.

Trait Implementations

impl Clone for RotaryEncoderEvent

fn clone(&self) -> RotaryEncoderEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RotaryEncoderEvent

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

Formats the value using the given formatter.

impl PartialEq for RotaryEncoderEvent

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