Enum VramHandle 

pub enum VramHandle {
    Empty,
    Rect(VramRect),
    Window(TextureWindowPlacement),
    RoomPage(u16),
    Clut {
        x: u16,
        y: u16,
        entries: u16,
    },
}

A freeable handle to a VRAM reservation handed out by VramAllocator.

Returned alongside the hardware TexturePage / Clut so a caller can both use the reservation immediately and release it later via VramAllocator::free. Copy so it can sit in fixed slot tables.

Variants

Empty

No reservation (allocation failed, or a default slot).

Rect(VramRect)

A coarse-grid rectangle: texture pages, model strips, the framebuffer.

Window(TextureWindowPlacement)

A room-material window inside the composed TextureWindowAtlas.

RoomPage(u16)

A whole reserved room-material page (its page index).

Clut

A CLUT-row sub-allocation: entries palette slots at (x, y).

Fields

x: u16

VRAM X (multiple of 16).

y: u16

VRAM Y.

entries: u16

Palette entry count (16 or 256).

Trait Implementations

impl Clone for VramHandle

fn clone(&self) -> VramHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VramHandle

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

Formats the value using the given formatter.

impl PartialEq for VramHandle

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

Tests for self and other values to be equal, and is used by ==.

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

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