Struct ExpertIndex 

pub struct ExpertIndex {
    pub version: u32,
    pub num_moe_layers: u32,
    pub num_experts: u32,
    pub inter: u64,
    pub hidden: u64,

}

2026-09-25: The store manifest, manifest.json beside the per-layer files: the geometry a reader needs to rebuild the spec and layout and open the files.

Fields

version: u32

2026-09-25: Must equal ExpertRecordHeader::VERSION for a reader to accept the store.

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

2026-09-25: Set to FILE_TEMPLATE by new; file_name does not read it.

moe_layer_to_model_layer: Vec<u32>

2026-09-25: Dense MoE-layer index → model layer index; new sets num_moe_layers to its length.

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>

2026-09-25: Read and version-check manifest.json from dir, without opening the layer files.

pub fn spec(&self) -> ExpertRecordSpec

pub fn layout(&self) -> ExpertLayout

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

2026-09-25: experts_{moe_layer:05}.xpr, whatever file_template holds.

pub fn total_bytes(&self) -> u64

2026-09-25: Bytes of all layer files together.

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.
