Struct JsSolver 

pub struct JsSolver { /* private fields */ }

Top-level solver handle exposed to JavaScript.

Wraps the algorithm router and iterative solvers, providing a high-level API that accepts CSR arrays directly from JS typed arrays.

Implementations

impl JsSolver

pub fn new() -> Self

Construct a new solver with default parameters.

• max_iterations: 1000
• tolerance: 1e-6
• alpha (PageRank teleport): 0.15

pub fn set_max_iterations(&mut self, max_iterations: usize)

Set the maximum number of iterations for iterative solvers.

pub fn set_tolerance(&mut self, tolerance: f64)

Set the convergence tolerance.

pub fn set_alpha(&mut self, alpha: f64)

Set the teleportation probability for PageRank.

pub fn solve( &self, values: &[f32], col_indices: &[u32], row_ptrs: &[u32], rows: usize, cols: usize, rhs: &[f32], ) -> Result<JsValue, JsError>

Solve a sparse linear system Ax = b.

The matrix A is provided in CSR format via three flat arrays. Returns a JSON-serialisable result object on success.

Arguments

• values - Non-zero values (Float32Array).
• col_indices - Column indices for each non-zero (Uint32Array).
• row_ptrs - Row pointers of length rows + 1 (Uint32Array).
• rows - Number of rows.
• cols - Number of columns.
• rhs - Right-hand side vector b (Float32Array).

Errors

Returns JsError on invalid input or non-convergence.

pub fn pagerank( &self, values: &[f32], col_indices: &[u32], row_ptrs: &[u32], rows: usize, source: usize, tolerance: f64, ) -> Result<JsValue, JsError>

Compute Personalized PageRank from a single source node.

Uses the power-iteration method with teleportation probability alpha (configurable via set_alpha).

Arguments

• values - Edge weights (Float32Array).
• col_indices - Column indices (Uint32Array).
• row_ptrs - Row pointers (Uint32Array).
• rows - Number of nodes.
• source - Source node index.
• tolerance - Convergence tolerance (L1 residual).

Errors

Returns JsError on invalid input.

pub fn estimate_complexity( &self, values: &[f32], col_indices: &[u32], row_ptrs: &[u32], rows: usize, cols: usize, ) -> Result<JsValue, JsError>

Estimate the computational complexity of solving a system with the given matrix without performing the actual solve.

Returns a JSON object with the selected algorithm, estimated FLOPS, estimated iterations, memory usage, and complexity class.

Trait Implementations

impl From<JsSolver> for JsValue

fn from(value: JsSolver) -> Self

Converts to this type from the input type.

impl FromWasmAbi for JsSolver

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 JsSolver

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 JsSolver

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<JsSolver>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for JsSolver

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 JsSolver

fn none() -> Self::Abi

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

impl RefFromWasmAbi for JsSolver

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<JsSolver>

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 JsSolver

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<JsSolver>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for JsSolver

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

Performs the conversion.

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