Struct PirBatch 

pub struct PirBatch {
    pub node_type: Vec<u8>,
    pub leaf_id: Vec<u32>,
    pub decision_var: Vec<u32>,
    pub decision_child_false: Vec<u32>,
    pub decision_child_true: Vec<u32>,
    pub child_offsets: Vec<u32>,
    pub children: Vec<u32>,
}

Host-side PIR batch (for tests and host-driven workflows).

Fields

node_type: Vec<u8>

Opcode for every candidate node.

leaf_id: Vec<u32>

Leaf identifier for every candidate literal node.

decision_var: Vec<u32>

Choice-variable identifier for every candidate decision node.

decision_child_false: Vec<u32>

False-branch child for every candidate decision node.

decision_child_true: Vec<u32>

True-branch child for every candidate decision node.

child_offsets: Vec<u32>

CSR offsets into Self::children.

children: Vec<u32>

Flattened child identifiers.

Implementations

impl PirBatch

pub fn len(&self) -> usize

Returns the number of candidate nodes.

pub fn is_empty(&self) -> bool

Returns whether the batch contains no candidate nodes.

pub fn and_or_batch(children: Vec<Vec<u32>>) -> Self

Build a batch of AND nodes with the given child lists.

This helper is primarily used by tests.

pub fn to_device( &self, provider: &Arc<CudaKernelProvider>, ) -> Result<GpuPirBatch>

Validates the batch layout and uploads it to the device.

Trait Implementations

impl Clone for PirBatch

fn clone(&self) -> PirBatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PirBatch

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

Formats the value using the given formatter.
