Struct ModelRouting 

pub struct ModelRouting {
    pub code: Option<String>,
    pub orchestrate: Option<String>,
    pub execute: Option<String>,
}

Task-type model routing — use different models for different task categories.

Example (pawan.toml)

[models]
code = "mistralai/mistral-small-4-119b-2603"     # best for code generation
orchestrate = "stepfun-ai/step-3.5-flash"         # best for tool calling
execute = "mlx-community/Qwen3.5-9B-OptiQ-4bit"  # fast local execution

Fields

code: Option<String>

Model for code generation tasks (implement, refactor, write tests)

orchestrate: Option<String>

Model for orchestration tasks (multi-step tool chains, analysis)

execute: Option<String>

Model for simple execution tasks (bash, write_file, cargo test)

Implementations

impl ModelRouting

pub fn route(&self, query: &str) -> Option<&str>

Select the best model for a given task based on keyword analysis. Returns None if no routing matches (use default model).

Trait Implementations

impl Clone for ModelRouting

fn clone(&self) -> ModelRouting

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModelRouting

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

Formats the value using the given formatter.

impl Default for ModelRouting

fn default() -> ModelRouting

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ModelRouting

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ModelRouting

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
