Internal trait implemented by each HTTP provider backend.

The generic HttpAgentProvider calls these methods to build requests, parse responses, and configure authentication. The agentic loop, retry, and timeout are handled by the wrapper.

Required Methods

fn provider_name(&self) -> &'static str

Provider name for logging and errors.

fn endpoint_url(&self, model: &str) -> String

Full endpoint URL for the given model.

fn auth_headers(&self) -> Vec<(String, String)>

Authentication and provider-specific headers.

fn build_request(&self, config: &AgentConfig) -> Result<Value, AgentError>

Build the initial JSON request body from an AgentConfig.

fn parse_response( &self, body: &Value, config: &AgentConfig, ) -> Result<TurnResult, AgentError>

Parse a non-streaming response body into a TurnResult.

fn parse_sse_line(&self, line: &str) -> Option<SseDelta>

Parse a single SSE data: line into a streaming delta.

fn fold_sse_deltas( &self, deltas: Vec<SseDelta>, config: &AgentConfig, ) -> Result<TurnResult, AgentError>

Fold accumulated SSE deltas into a complete TurnResult.

fn compute_cost( &self, model: &str, input_tokens: u64, output_tokens: u64, ) -> Option<f64>

Compute cost in USD from token counts. Returns None if unknown.

fn resolve_model(&self, model: &str) -> String

Resolve model alias (e.g. “sonnet”) to a provider-specific model ID.

Dyn Compatibility

This trait is dyn compatible.

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