Module bedrock 

Amazon Bedrock provider for the Converse API.

Supports both AWS IAM SigV4 credentials and opaque bearer tokens (e.g. from an API Gateway fronting Bedrock). Dispatches chat completions, tool calls, and model discovery via the bedrock-runtime and bedrock management APIs.

Quick Start

use codetether_agent::provider::Provider;
use codetether_agent::provider::bedrock::{AwsCredentials, BedrockProvider};

let creds = AwsCredentials::from_environment().expect("creds");
let region = AwsCredentials::detect_region().unwrap_or_else(|| "us-west-2".into());
let provider = BedrockProvider::with_credentials(creds, region).unwrap();
let models = provider.list_models().await.unwrap();
assert!(!models.is_empty());

Architecture

• auth — credential loading, SigV4/bearer auth mode enum
• aliases — short-name to full model ID mapping
• sigv4 — SigV4 signing + HTTP dispatch
• estimates — context-window / max-output heuristics
• convert — [Message] → Converse API JSON translation
• body — Converse request body builder
• response — Converse response parser
• discovery — dynamic model list via management APIs
