}

One of the RDP’s eight tile descriptors.

The format/size/addressing state that binds a region of TMEM to a texture, set by Set Tile (0x35) and sized by Set Tile Size (0x32) / the load commands. All fields are decoded straight from the command word (N64brew …/Commands §0x35/§0x32).

Fields

format: u8

Texel format: RGBA=0, YUV=1, CI=2, IA=3, I=4 (Set Tile bits 55:53).

size: u8

Texel size code: 4bpp=0, 8bpp=1, 16bpp=2, 32bpp=3 (bits 52:51).

line: u16

Row stride in 64-bit TMEM words (bits 49:41).

tmem_addr: u16

Base TMEM address in 64-bit words (bits 40:32); word 0x100 = byte 0x800.

palette: u8

Palette index, the high half of the TLUT address for CI4 tiles only (bits 23:20).

clamp_t: bool

Clamp T when sampling outside the tile (bit 19).

mirror_t: bool

Mirror T on every other wrap (bit 18).

mask_t: u8

Number of T integer-coordinate bits used for wrap; 0 = all (bits 17:14).

shift_t: u8

T coordinate shift code, per the shift table (bits 13:10).

clamp_s: bool

Clamp S when sampling outside the tile (bit 9).

mirror_s: bool

Mirror S on every other wrap (bit 8).

mask_s: u8

Number of S integer-coordinate bits used for wrap; 0 = all (bits 7:4).

shift_s: u8

S coordinate shift code, per the shift table (bits 3:0).

sl: u16

Tile-size upper-left S (u10.2), from Set Tile Size / the loaders.

tl: u16

Tile-size upper-left T (u10.2).

sh: u16

Tile-size lower-right S (u10.2).

th: u16

Tile-size lower-right T (u10.2).

Trait Implementations

impl Clone for TileDescriptor

fn clone(&self) -> TileDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TileDescriptor

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

Formats the value using the given formatter.

impl Default for TileDescriptor

fn default() -> TileDescriptor

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TileDescriptor

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TileDescriptor

fn eq(&self, other: &TileDescriptor) -> 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.

impl Serialize for TileDescriptor

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TileDescriptor
