Struct BedrockDriver 

pub struct BedrockDriver { /* private fields */ }

Driver for AWS Bedrock using the Converse API with SigV4 authentication.

Implementations

impl BedrockDriver

pub fn new(access_key: String, secret_key: String, region: String) -> Self

Create a new Bedrock driver.

pub fn with_client( client: Client, access_key: String, secret_key: String, region: String, ) -> Self

Create a new Bedrock driver with a shared HTTP client.

pub fn build_request_body(&self, request: &CompletionRequest) -> Value

Build the Bedrock Converse API request body.

pub fn build_url(&self, model_id: &str) -> String

Build the endpoint URL for a model.

pub fn parse_response(&self, body: &Value) -> PunchResult<CompletionResponse>

Parse the Bedrock Converse API response.

pub fn sign_request( &self, method: &str, url: &str, headers: &[(String, String)], payload: &[u8], timestamp: &str, ) -> PunchResult<String>

Compute an AWS SigV4 signature and return the Authorization header value.

This is a basic implementation sufficient for Bedrock API calls.

Trait Implementations

impl LlmDriver for BedrockDriver

fn complete<'life0, 'async_trait>( &'life0 self, request: CompletionRequest, ) -> Pin<Box<dyn Future<Output = PunchResult<CompletionResponse>> + Send + 'async_trait>>

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

Send a completion request and return the response.

fn stream_complete_with_callback<'life0, 'async_trait>( &'life0 self, request: CompletionRequest, callback: StreamCallback, ) -> Pin<Box<dyn Future<Output = PunchResult<CompletionResponse>> + Send + 'async_trait>>

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

Streaming completion with per-chunk callback. Returns the final assembled CompletionResponse.

fn stream_complete<'life0, 'async_trait>( &'life0 self, request: CompletionRequest, ) -> Pin<Box<dyn Future<Output = PunchResult<CompletionResponse>> + Send + 'async_trait>>

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

Streaming variant. Default implementation falls back to complete.
