Struct BedrockConfig 

pub struct BedrockConfig {
    pub region: String,
    pub model_id: String,
    pub endpoint_url: Option<String>,
    pub prompt_caching: Option<BedrockCacheConfig>,
}

Available on crate feature models only.

Configuration for Amazon Bedrock.

Bedrock uses AWS IAM/STS authentication rather than API keys. Credentials are loaded from the environment via the AWS SDK (environment variables, shared config, IMDS, etc.).

Prompt caching is enabled by default with a 5-minute TTL. Use without_prompt_caching to disable.

Inference Profiles

Newer Bedrock models require cross-region inference profile IDs (prefixed with us. or global.) instead of raw model IDs.

Example

use adk_model::bedrock::BedrockConfig;

// Default: us-east-1, Claude Sonnet 4.6, prompt caching enabled
let config = BedrockConfig::default();

// Custom region and model
let config = BedrockConfig::new("eu-west-1", "us.anthropic.claude-haiku-4-5-20251001-v1:0");

// With a custom endpoint (e.g., VPC endpoint)
let config = BedrockConfig::new("us-west-2", "us.anthropic.claude-sonnet-4-6")
    .with_endpoint_url("https://vpce-xxx.bedrock-runtime.us-west-2.vpce.amazonaws.com");

// Disable prompt caching
let config = BedrockConfig::default().without_prompt_caching();

Fields

region: String

AWS region for the Bedrock endpoint (e.g., "us-east-1").

model_id: String

Bedrock model identifier (e.g., "us.anthropic.claude-sonnet-4-6").

endpoint_url: Option<String>

Optional custom endpoint URL (e.g., a VPC endpoint).

prompt_caching: Option<BedrockCacheConfig>

Optional prompt caching configuration.

Defaults to Some(BedrockCacheConfig::default()) (5-minute TTL). When set, the Bedrock request builder injects CachePoint blocks after system prompts and tool definitions in the Converse API request. Use without_prompt_caching to disable.

Implementations

impl BedrockConfig

pub fn new( region: impl Into<String>, model_id: impl Into<String>, ) -> BedrockConfig

Available on crate feature bedrock only.

Create a new Bedrock config with the given region and model ID.

pub fn with_endpoint_url(self, url: impl Into<String>) -> BedrockConfig

Available on crate feature bedrock only.

Set a custom endpoint URL (e.g., a VPC endpoint).

pub fn with_prompt_caching(self, config: BedrockCacheConfig) -> BedrockConfig

Available on crate feature bedrock only.

Enable prompt caching with the given configuration.

When enabled, the Bedrock request builder injects CachePoint blocks after system prompts and tool definitions in the Converse API request.

Example

use adk_model::bedrock::{BedrockConfig, BedrockCacheConfig, BedrockCacheTtl};

let config = BedrockConfig::default()
    .with_prompt_caching(BedrockCacheConfig { ttl: BedrockCacheTtl::FiveMinutes });

pub fn without_prompt_caching(self) -> BedrockConfig

Available on crate feature bedrock only.

Disable prompt caching.

By default, prompt caching is enabled with a 5-minute TTL. Call this method to opt out of automatic caching.

Example

use adk_model::bedrock::BedrockConfig;

let config = BedrockConfig::default().without_prompt_caching();
assert!(config.prompt_caching.is_none());
