/// Client for Amazon DynamoDB
///
/// Client for invoking operations on Amazon DynamoDB. Each operation on Amazon DynamoDB is a method on this
/// this struct. `.send()` MUST be invoked on the generated operations to dispatch the request to the service.
/// ## Constructing a `Client`
///
/// A [`Config`] is required to construct a client. For most use cases, the [`aws-config`]
/// crate should be used to automatically resolve this config using
/// [`aws_config::load_from_env()`], since this will resolve an [`SdkConfig`] which can be shared
/// across multiple different AWS SDK clients. This config resolution process can be customized
/// by calling [`aws_config::from_env()`] instead, which returns a [`ConfigLoader`] that uses
/// the [builder pattern] to customize the default config.
///
/// In the simplest case, creating a client looks as follows:
/// ```rust,no_run
/// # async fn wrapper() {
/// let config = aws_config::load_from_env().await;
/// let client = aws_sdk_dynamodb::Client::new(&config);
/// # }
/// ```
///
/// Occasionally, SDKs may have additional service-specific values that can be set on the [`Config`] that
/// is absent from [`SdkConfig`], or slightly different settings for a specific client may be desired.
/// The [`Builder`](crate::config::Builder) struct implements `From<&SdkConfig>`, so setting these specific settings can be
/// done as follows:
///
/// ```rust,no_run
/// # async fn wrapper() {
/// let sdk_config = ::aws_config::load_from_env().await;
/// let config = aws_sdk_dynamodb::config::Builder::from(&sdk_config)
/// # /*
///     .some_service_specific_setting("value")
/// # */
///     .build();
/// # }
/// ```
///
/// See the [`aws-config` docs] and [`Config`] for more information on customizing configuration.
///
/// _Note:_ Client construction is expensive due to connection thread pool initialization, and should
/// be done once at application start-up.
///
/// [`Config`]: crate::Config

/// [builder pattern]: https://rust-lang.github.io/api-guidelines/type-safety.html#builders-enable-construction-of-complex-values-c-builder
/// # Using the `Client`
///
/// A client has a function for every operation that can be performed by the service.
/// For example, the [`BatchExecuteStatement`](crate::operation::batch_execute_statement) operation has
/// a [`Client::batch_execute_statement`], function which returns a builder for that operation.
/// The fluent builder ultimately has a `send()` function that returns an async future that
/// returns a result, as illustrated below:
///
/// ```rust,ignore
/// let result = client.batch_execute_statement()
///     .return_consumed_capacity("example")
///     .send()
///     .await;
/// ```
///
/// The underlying HTTP requests that get made by this can be modified with the `customize_operation`
/// function on the fluent builder. See the [`customize`](crate::client::customize) module for more
/// information.
/// # Waiters
///
/// This client provides `wait_until` methods behind the [`Waiters`](crate::client::Waiters) trait.
/// To use them, simply import the trait, and then call one of the `wait_until` methods. This will
/// return a waiter fluent builder that takes various parameters, which are documented on the builder
/// type. Once parameters have been provided, the `wait` method can be called to initiate waiting.
///
/// For example, if there was a `wait_until_thing` method, it could look like:
/// ```rust,ignore
/// let result = client.wait_until_thing()
///     .thing_id("someId")
///     .wait(Duration::from_secs(120))
///     .await;
/// ```
