Struct ExpertIndex 

pub struct ExpertIndex {
    pub version: u32,
    pub num_moe_layers: u32,
    pub num_experts: u32,
    pub inter: u64,
    pub hidden: u64,
    pub group_size: u64,
    pub sub_align: u64,
    pub fs_block_size: u64,
    pub record_stride: u64,
    pub record_raw_bytes: u64,
    pub file_template: String,
    pub moe_layer_to_model_layer: Vec<u32>,
}

Directory manifest describing a built expert store. Serialized as manifest.json next to the per-layer .xpr files. This is the streamer’s entry point — everything it needs to reconstruct geometry and open files.

Fields

version: u32

Format version; must equal ExpertRecordHeader::VERSION.

num_moe_layers: u32

num_experts: u32

inter: u64

hidden: u64

group_size: u64

sub_align: u64

fs_block_size: u64

record_stride: u64

record_raw_bytes: u64

file_template: String

printf-style template for per-layer file names, e.g. experts_{:05}.xpr.

moe_layer_to_model_layer: Vec<u32>

Dense MoE-layer index -> absolute model layer index. Lets the runtime map a model layer back to its expert file (dense attention layers are absent).

Implementations

impl ExpertIndex

pub const FILE_TEMPLATE: &'static str = "experts_{:05}.xpr"

pub const MANIFEST_NAME: &'static str = "manifest.json"

pub fn new( inter: u64, hidden: u64, group_size: u64, sub_align: u64, fs_block_size: u64, moe_layer_to_model_layer: Vec<u32>, num_experts: u32, ) -> Self

pub fn load(dir: &Path) -> Result<Self>

Load just the manifest (manifest.json) from a store dir — geometry only, no file handles. Lets the streamer size its arena before opening a tier. Validates the format version.

pub fn spec(&self) -> ExpertRecordSpec

pub fn layout(&self) -> ExpertLayout

pub fn file_name(&self, moe_layer: u32) -> String

Per-layer file name for a dense MoE-layer index.

pub fn total_bytes(&self) -> u64

Total on-disk bytes across all layer files.

Trait Implementations

impl Clone for ExpertIndex

fn clone(&self) -> ExpertIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpertIndex

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExpertIndex

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ExpertIndex

fn eq(&self, other: &ExpertIndex) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ExpertIndex

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
