Struct ChunkGeometry 

pub struct ChunkGeometry { /* private fields */ }

Physical payload geometry available to one exchange direction.

Runtime policy chooses how many slots one publication should span. The resulting chunk capacity is always an exact multiple of the physical slot payload size: slots * slot_payload_bytes.

Implementations

impl ChunkGeometry

pub const fn new( slot_payload_bytes: usize, slots_per_lane: usize, ) -> Option<Self>

pub const fn slot_payload_bytes(self) -> usize

Usable payload bytes in one physical slot. Slot metadata lives outside this capacity.

pub const fn slots_per_lane(self) -> usize

Maximum slots one publication may reserve from this node’s lane.

pub const fn chunk_bytes(self, slots: usize) -> Option<usize>

Exact publication capacity for a runtime-selected slot count.

pub const fn slots_for_target(self, target_bytes: usize) -> Option<usize>

Convert a byte target into a valid runtime slot count. The target is rounded down to whole slots, but never below one slot, and clamped to the node lane.

pub const fn chunk_bytes_for_target(self, target_bytes: usize) -> Option<usize>

Effective chunk capacity for a runtime byte target. This is always n * slot_payload_bytes for a valid lane-bounded n.

pub const fn plan( self, data_bytes: usize, slots_per_chunk: usize, ) -> Option<ChunkPlan>

Plan a known payload using a runtime-selected slot count.

pub const fn plan_for_target( self, data_bytes: usize, target_bytes: usize, ) -> Option<ChunkPlan>

Plan a known payload from a runtime byte target after aligning it to the physical slot payload geometry.
