Struct BlockTable 

pub struct BlockTable { /* private fields */ }

Maps a sequence’s logical block indices to physical page indices.

Each transformer layer has its own independent list of physical blocks so that cross-layer sharing is straightforward to reason about.

Implementations

impl BlockTable

pub fn new(num_layers: usize, block_size: usize) -> Self

Create an empty block table for num_layers layers.

pub fn append_block(&mut self, layer: usize, physical_idx: usize)

Append a newly-allocated physical page to layer’s block list.

Panics

Panics in debug builds if layer >= num_layers.

pub fn get_block(&self, layer: usize, logical_block: usize) -> Option<usize>

Look up the physical page index for logical block logical_block in layer.

Returns None if either the layer or the logical block index is out of range.

pub fn num_blocks(&self, layer: usize) -> usize

Number of physical blocks currently mapped for layer.

Returns 0 for out-of-range layer.

pub fn token_capacity(&self, layer: usize) -> usize

Total token capacity (may include unused trailing slots) for layer.
