Struct JsTensorCompress 

pub struct JsTensorCompress { /* private fields */ }

Tensor compressor with adaptive level selection

Implementations

impl JsTensorCompress

pub fn new() -> Self

Create a new tensor compressor

pub fn compress( &self, embedding: Vec<f32>, access_freq: f32, ) -> Result<JsValue, JsValue>

Compress an embedding based on access frequency

Arguments

• embedding - The input embedding vector (Float32Array)
• access_freq - Access frequency in range [0.0, 1.0]
  • f > 0.8: Full precision (hot data)
  • f > 0.4: Half precision (warm data)
  • f > 0.1: 8-bit PQ (cool data)
  • f > 0.01: 4-bit PQ (cold data)
  • f <= 0.01: Binary (archive)

Returns

Compressed tensor as JsValue

pub fn compress_with_level( &self, embedding: Vec<f32>, level: &str, ) -> Result<JsValue, JsValue>

Compress with explicit compression level

Arguments

• embedding - The input embedding vector
• level - Compression level (“none”, “half”, “pq8”, “pq4”, “binary”)

Returns

Compressed tensor as JsValue

pub fn decompress(&self, compressed: JsValue) -> Result<Vec<f32>, JsValue>

Decompress a compressed tensor

Arguments

• compressed - Serialized compressed tensor (JsValue)

Returns

Decompressed embedding vector (Float32Array)

pub fn get_compression_ratio(&self, access_freq: f32) -> f32

Get compression ratio estimate for a given access frequency

Arguments

• access_freq - Access frequency in range [0.0, 1.0]

Returns

Estimated compression ratio (original_size / compressed_size)

Trait Implementations

impl From<JsTensorCompress> for JsValue

fn from(value: JsTensorCompress) -> Self

Converts to this type from the input type.

impl FromWasmAbi for JsTensorCompress

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for JsTensorCompress

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for JsTensorCompress

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<JsTensorCompress>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for JsTensorCompress

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for JsTensorCompress

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for JsTensorCompress

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<JsTensorCompress>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for JsTensorCompress

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<JsTensorCompress>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for JsTensorCompress

fn try_from_js_value(value: JsValue) -> Result<Self, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<Self>

Performs the conversion.

impl VectorFromWasmAbi for JsTensorCompress

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[JsTensorCompress]>

impl VectorIntoWasmAbi for JsTensorCompress

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

fn vector_into_abi(vector: Box<[JsTensorCompress]>) -> Self::Abi
