Struct ClientBuilder 

pub struct ClientBuilder<'a> {
    region: &'a str,
    compat: &'a CompatFlags,
    proxy: &'a ProxyConfig,
    credentials_provider: Option<SharedCredentialsProvider>,
    notification_log: Option<NotificationLogHandle>,
}

Parameters needed to build one aws_sdk_s3::Client.

Separated from ClientPool so tests can construct clients directly without standing up a pool.

Fields

region: &'a str

compat: &'a CompatFlags

proxy: &'a ProxyConfig

credentials_provider: Option<SharedCredentialsProvider>

Optional explicit credentials provider. When None the SDK default provider chain is used (env → profile → IMDSv2 → …).

notification_log: Option<NotificationLogHandle>

Optional notification log to push compat-flag warnings into. When None, warnings are only emitted via tracing::warn!.

Implementations

impl<'a> ClientBuilder<'a>

pub fn new( region: &'a str, compat: &'a CompatFlags, proxy: &'a ProxyConfig, ) -> Self

Create a builder for the given region and compatibility flags.

pub fn credentials_provider(self, provider: SharedCredentialsProvider) -> Self

Override the credential provider (useful in tests or for manual profiles).

pub fn notification_log(self, handle: NotificationLogHandle) -> Self

Attach a notification log handle so compat-flag warnings are surfaced to the user through the in-app notification system (task 9).

When not set, warnings are logged via tracing::warn! only.

pub async fn build(self) -> Client

Build the aws_sdk_s3::Client.

This is async because aws_config::load_from_env() is async.
