Struct KeywordRouter 

pub struct KeywordRouter { /* private fields */ }

A keyword-based router with configurable rules and a default fallback.

Rules map keyword patterns (matched case-insensitively against the prompt) to a preferred BackendType. The first matching rule wins. If no rules match, the default backend is used.

By default, keywords are matched as substrings. Enable word_boundary to require that keywords appear as whole words (e.g., “test” won’t match “testing”).

Example

use agent_teams::backend::router::KeywordRouter;
use agent_teams::BackendType;

let router = KeywordRouter::new(BackendType::ClaudeCode)
    .word_boundary(true)
    .rule("review", BackendType::GeminiCli)
    .rule("analyze", BackendType::GeminiCli)
    .rule("implement", BackendType::ClaudeCode)
    .rule("test", BackendType::Codex);

Implementations

impl KeywordRouter

pub fn new(default: BackendType) -> Self

Create a new keyword router with a default backend.

pub fn word_boundary(self, enable: bool) -> Self

Enable or disable word-boundary matching.

When enabled, “test” matches “test this code” but NOT “testing this code”. Default is false (substring matching) for backward compatibility.

pub fn rule(self, keyword: impl Into<String>, backend: BackendType) -> Self

Add a keyword → backend rule. Keywords are matched case-insensitively against the SpawnConfig::prompt field.

pub fn rules( self, rules: impl IntoIterator<Item = (String, BackendType)>, ) -> Self

Add multiple rules from an iterator of (keyword, backend) pairs.

Trait Implementations

impl BackendRouter for KeywordRouter

fn route<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, config: &'life1 SpawnConfig, available: &'life2 [BackendType], ) -> Pin<Box<dyn Future<Output = Option<BackendType>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Choose the optimal backend for the given config.

impl Debug for KeywordRouter

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

Formats the value using the given formatter.
