Struct StaticPacket 

pub struct StaticPacket<const W: usize> { /* private fields */ }

One immutable linked-list node: W GP0 words, then the end of the list.

Built in a static, it is a chain that stays valid for the whole run, so crate::Gpu::submit_static can kick it from safe code without waiting.

use psx_gpu::chain::StaticPacket;
// GP0(E1h) draw mode, then GP0(1Fh).
static MODE_THEN_IRQ: StaticPacket<2> = StaticPacket::new([0xE100_0000, 0x1F00_0000]);
assert_eq!(MODE_THEN_IRQ.words(), &[0xE100_0000, 0x1F00_0000]);

Implementations

impl<const W: usize> StaticPacket<W>

pub const fn words(&self) -> &[u32; W]

The payload words.

pub fn as_ptr(&self) -> *const u32

The node’s tag word, the address a chain links to.
