Struct ScanBodyPlan 

pub struct ScanBodyPlan {
    pub body: ThunkSchedule,
    pub body_init: Vec<u8>,
    pub body_input_off: usize,
    pub body_output_off: usize,
    pub carry_bytes: usize,
    pub bcast_body_offs: Vec<usize>,
    pub xs_body_offs: Vec<usize>,
}

A scan body compiled into a self-contained CPU schedule plus the byte offsets needed to drive it. Backends without a native Op::Scan kernel (e.g. Metal via the unified-memory host fallback) build this once at compile time and hand it to execute_scan_host at run time. Mirrors the inline Op::Scan compilation used by the CPU executor.

Fields

body: ThunkSchedule

body_init: Vec<u8>

body_input_off: usize

body_output_off: usize

carry_bytes: usize

bcast_body_offs: Vec<usize>

Body-arena offsets of the broadcast inputs, in declaration order.

xs_body_offs: Vec<usize>

Body-arena offsets of the per-step (xs) inputs, in declaration order.
