Struct Pressure 

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

How hard a key or a channel is being pressed after the note started.

A seven-bit value: 0 to 127, which is what one MIDI data byte carries.

Implementations

impl Pressure

pub const MIN: Self

The smallest value, 0.

pub const MAX: Self

The largest value, 127.

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

A pressure, or None above 127.

Rejecting is the point: the wire cannot carry the eighth bit, and the alternative — masking it off, as Bela’s own writeMessage does — turns a number that was wrong into a different number that is not.

pub const fn get(self) -> u8

The value, 0 to 127.

Trait Implementations

impl Clone for Pressure

fn clone(&self) -> Pressure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Pressure

impl Debug for Pressure

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

Formats the value using the given formatter.

impl Default for Pressure

fn default() -> Pressure

Returns the “default value” for a type.

impl Display for Pressure

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

Formats the value using the given formatter.

impl Eq for Pressure

impl From<Pressure> for u8

fn from(value: Pressure) -> Self

Converts to this type from the input type.

impl Hash for Pressure

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Pressure

fn cmp(&self, other: &Pressure) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Pressure

fn eq(&self, other: &Pressure) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Pressure

fn partial_cmp(&self, other: &Pressure) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StructuralPartialEq for Pressure

impl TryFrom<u8> for Pressure

fn try_from(value: u8) -> Result<Self, Self::Error>

A pressure, or Error::MidiValue above 127.

The same check as new, for code that converts generically. new stays because a range check with one way to fail says as much with Option.

type Error = Error

The type returned in the event of a conversion error.
