Implementations

impl ChannelMessageType

pub fn in_channel(self, channel: u8) -> Option<ChannelMessage>

Creates a new ChannelMessage from self with the given channel.

None is returned if the channel value is outside the range [0..16).

Examples

let message_type = ChannelMessageType::NoteOn {
        key: 77,
        velocity: 88
    };
let message = message_type.in_channel(15).unwrap();

assert_eq!(message.channel(), 15);
assert_eq!(message.message_type(), message_type);

let channel_out_of_range = message_type.in_channel(16);
assert!(channel_out_of_range.is_none());

Trait Implementations

impl Clone for ChannelMessageType

fn clone(&self) -> ChannelMessageType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelMessageType

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

Formats the value using the given formatter.

impl PartialEq for ChannelMessageType

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
