Struct SemanticRouter 

pub struct SemanticRouter { /* private fields */ }

Routes prompts to specialised workers using keyword-based heuristics.

The router is stateless — all routing decisions are computed from the prompt text alone, making it safe to share across threads via Arc.

Example

use tokio_prompt_orchestrator::routing::semantic::{SemanticRouter, RoutingCategory};

let router = SemanticRouter::default();
assert_eq!(
    router.classify("Write a recursive Fibonacci function in Rust"),
    RoutingCategory::Code,
);

Implementations

impl SemanticRouter

pub fn new() -> Self

Create a router with default configuration.

Panics

This function does not panic.

pub fn with_config(config: SemanticRouterConfig) -> Self

Create a router with custom configuration.

Panics

This function does not panic.

pub fn classify(&self, prompt: &str) -> RoutingCategory

Classify a prompt into a RoutingCategory.

Returns RoutingCategory::General when no category reaches the configured min_matches threshold, or when the prompt is empty.

Panics

This function does not panic.

pub fn classify_detailed(&self, prompt: &str) -> ClassificationResult

Classify a prompt and return a full ClassificationResult.

Useful for diagnostics, logging, and metrics.

Panics

This function does not panic.

pub fn route(&self, prompt: &str) -> String

Classify a prompt and return the target worker label string.

This is the primary method callers use to decide where to send a request.

Panics

This function does not panic.

pub fn worker_label_for(&self, category: RoutingCategory) -> String

Return the configured worker label for a given category, falling back to the default if no override is configured.

Panics

This function does not panic.

Trait Implementations

impl Clone for SemanticRouter

fn clone(&self) -> SemanticRouter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SemanticRouter

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

Formats the value using the given formatter.

impl Default for SemanticRouter

fn default() -> SemanticRouter

Returns the “default value” for a type.
