Struct PayloadArenaSpec 

pub struct PayloadArenaSpec {
    pub kind: u8,
    pub slots_per_node: usize,
    pub slot_size: usize,
}

Geometry and SHM identity of one fleet-wide payload arena.

Fields

kind: u8

slots_per_node: usize

Physical allocation units available to each fleet node.

slot_size: usize

Bytes in one physical allocation unit.

Implementations

impl PayloadArenaSpec

pub const fn new(kind: u8, slots_per_node: usize, slot_size: usize) -> Self

pub const fn lane_bytes(self) -> usize

pub const fn slots_for(self, payload_len: usize) -> usize

pub const fn chunk_geometry(self) -> Option<ChunkGeometry>

Physical chunk geometry for this arena. Runtime policy chooses the slot count independently for each request or response.

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

Plan a known payload with the benchmark-backed default chunk target, clamped so one chunk always fits in this node lane.

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

Plan using a runtime-selected number of slots per publication.
