Basic Usage

use midi2::prelude::*;

let mut message = flex_data::ProjectName::<Vec<u32>>::new();
message.set_text("Shadows of the Forgotten Cathedral");

let mut packets = message.packets();

assert_eq!(packets.next(), Some(&[0xD0500101, 0x53686164, 0x6F777320, 0x6F662074][..]));
assert_eq!(packets.next(), Some(&[0xD0900101, 0x68652046, 0x6F72676F, 0x7474656E][..]));
assert_eq!(packets.next(), Some(&[0xD0D00101, 0x20436174, 0x68656472, 0x616C0000][..]));
assert_eq!(packets.next(), None);

Packets may be shorter than 128 bytes for certain messages which are represented by shorter packets.

use midi2::prelude::*;

let mut message = sysex7::Sysex7::<Vec<u32>>::new();
message.set_payload((0..20).map(u7::new));

let mut packets = message.packets();

assert_eq!(packets.next(), Some(&[0x30160001, 0x2030405][..]));
assert_eq!(packets.next(), Some(&[0x30260607, 0x8090A0B][..]));
assert_eq!(packets.next(), Some(&[0x30260C0D, 0xE0F1011][..]));
assert_eq!(packets.next(), Some(&[0x30321213, 0x0][..]));
assert_eq!(packets.next(), None);
