Trait Provider 

pub trait Provider: Send + Sync {
    // Required method
    fn stream<'life0, 'life1, 'life2, 'life3, 'life4, 'async_trait>(
        &'life0 self,
        model: &'life1 str,
        system_prompt: &'life2 str,
        messages: &'life3 [AgentMessage],
        tools: &'life4 [ToolDef],
    ) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = StreamEvent> + Send>>>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait,
             'life2: 'async_trait,
             'life3: 'async_trait,
             'life4: 'async_trait;

    // Provided method
    fn set_reasoning_effort(&self, _level: Option<&str>) { ... }
}

The one thing the agent loop needs from a provider.

Required Methods

fn stream<'life0, 'life1, 'life2, 'life3, 'life4, 'async_trait>( &'life0 self, model: &'life1 str, system_prompt: &'life2 str, messages: &'life3 [AgentMessage], tools: &'life4 [ToolDef], ) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = StreamEvent> + Send>>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, 'life4: 'async_trait,

Provided Methods

fn set_reasoning_effort(&self, _level: Option<&str>)

Update reasoning effort (thinking level) at runtime. Default implementation is a no-op for providers that don’t support this.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
