pub struct QuartersPerMinute(/* private fields */);
Expand description

A more convenient way to specify tempo, not part of the MIDI spec. This is closer to the way we think of tempo, e.g. “120 Beats per Minute”. This type is locked to quarter-notes so you will have to translate if your “beat” is not a quarter note. Any u8 greater than zero is valid.

Implementations§

source§

impl QuartersPerMinute

source

pub const fn new(value: u8) -> Self

Silently clamps the value if it is out of range. See Self::set.

source

pub fn get(&self) -> u8

Returns the inner value.

source

pub fn set(&mut self, value: u8) -> bool

Clamps and sets. Returns true if value was in range. Returns false if value was out-of-range. That is, given a valid range of 1..=5, then set(0) will set the value to 1 and return false. set(4) will set the value to 4 and return true.
