Struct ReliableProvider 

pub struct ReliableProvider { /* private fields */ }

Provider wrapper with retry, fallback, auth rotation, and model failover.

Implementations

impl ReliableProvider

pub fn new( providers: Vec<(String, Box<dyn ModelProvider>)>, max_retries: u32, base_backoff_ms: u64, ) -> Self

pub fn with_api_keys(self, keys: Vec<String>) -> Self

Set additional API keys for round-robin rotation on rate-limit errors.

pub fn with_model_fallbacks( self, fallbacks: HashMap<String, Vec<String>>, ) -> Self

Set per-model fallback chains.

Trait Implementations

impl ModelProvider for ReliableProvider

fn warmup<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Warm up the HTTP connection pool (TLS handshake, DNS, HTTP/2 setup). Default implementation is a no-op; providers with HTTP clients should override.

fn chat<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, request: ChatRequest<'life1>, model: &'life2 str, temperature: f64, ) -> Pin<Box<dyn Future<Output = Result<ChatResponse>> + Send + 'async_trait>>

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

Structured chat API — the single required method.

fn chat_stream<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, request: ChatRequest<'life1>, model: &'life2 str, temperature: f64, events: UnboundedSender<ProviderStreamEvent>, ) -> Pin<Box<dyn Future<Output = Result<ChatResponse>> + Send + 'async_trait>>

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

Optional streaming chat API.

fn context_window(&self, model: &str) -> Option<usize>

Context window size in tokens for the given model.

fn supports_native_tools(&self) -> bool

Whether provider supports native tool calls over API.

fn supports_developer_role(&self, model: &str) -> bool

Whether the given model supports the developer message role (OpenAI-spec). When true, app-owned instructions are sent as a developer message. When false, they are folded into the provider’s system-equivalent role.

fn native_capabilities(&self) -> Option<ProviderNativeCapabilities>

Provider-native capabilities outside the chat/tool turn loop.

fn submit_media<'life0, 'async_trait>( &'life0 self, request: NativeMediaRequest, ) -> Pin<Box<dyn Future<Output = Result<NativeMediaResponse>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Submit a provider-native media operation.

fn poll_media_job<'life0, 'life1, 'async_trait>( &'life0 self, job: &'life1 NativeMediaJob, ) -> Pin<Box<dyn Future<Output = Result<NativeMediaResponse>> + Send + 'async_trait>>

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

Poll an async provider-native media job.
