Struct IndirectTile 

pub struct IndirectTile {
    pub index: BufferId,
    pub tile_stride: usize,
    pub elems_per_tile: usize,
    pub bound: (usize, usize),
}

A value-dependent tile address: the tile is chosen by an INDEX read from a buffer, not by the loop variables — an embedding row, a KV-cache slot, a flash-attention block, a chosen expert’s weights.

Semantics: the index v is element 0 of the index buffer’s front page (the buffer is an operand of the Load or Store; the schedule waits on it before the transfer and retires it after); the address gains (v div elems_per_tile) · tile_stride tiles. A v outside bound (or not a whole number) is a fault in the data run, never a wrapped row; the token-only dry run, which has no index to read, checks the tile block at BOTH ends of bound against the tensor, so a certificate covers every index the bound admits. Printers with no gather instruction refuse it by name (SpatialProgram::has_indirect_access).

Fields

index: BufferId

The buffer whose front page carries the index.

tile_stride: usize

Tiles per unit of index (a row of tile_stride tiles per indexed row).

elems_per_tile: usize

Elements a unit of index spans — how the index is scaled before it is tile-aligned.

bound: (usize, usize)

The declared inclusive range of the index; a gather without one earns no certificate (B-P5).

Trait Implementations

impl Clone for IndirectTile

fn clone(&self) -> IndirectTile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndirectTile

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IndirectTile

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for IndirectTile

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for IndirectTile

fn eq(&self, other: &IndirectTile) -> 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 IndirectTile

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
