Struct RouteTable 

pub struct RouteTable { /* private fields */ }

Implementations

impl RouteTable

pub fn from_toml_str(s: &str) -> Result<Self>

pub fn jev_route(&self, model: &str) -> Option<&JevRoute>

The tiers and decision settings of a strategy = "jev" route.

pub fn legs(&self, model: &str) -> Option<&[ChainLeg]>

Ordered legs for a model alias, or None if the alias is unknown.

pub fn policy_of(&self, model: &str) -> Option<&str>

Policy name selected by a route alias, or None when unset.

pub fn aliases(&self) -> Vec<String>

All registered aliases (for /v1/models), sorted for stable output.

pub fn referenced_providers(&self) -> HashSet<String>

Provider ids referenced by any leg, plus typesafe when a jev route needs Jev to decide (for fail-fast credential validation).

pub fn without_providers(&self, drop: &HashSet<String>) -> Self

This table with every leg belonging to drop removed, and any route left with no legs removed entirely.

A multi-leg route survives on its remaining legs, so a route whose first choice is unavailable degrades to its fallback instead of disappearing. A jev route prunes inside its tiers; it becomes a static route when typesafe is dropped or fewer than two tiers survive.

pub fn vertex_fallback_chain(&self, model: &str) -> VertexPassthroughChain

Consecutive Vertex legs for Gemini-native passthrough fallback.

Prefer a route whose first leg is vertex + model (lexicographically first alias if several match). Otherwise start at the first matching vertex leg in the lex-first route that contains it. Stop before the first non-vertex leg. If nothing matches, return a single synthetic leg so callers always have ≥1 attempt (same as today’s single forward). jev routes never take part: their legs span difficulty tiers, not fallbacks for one model.
