25//! Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. DynamoDB lets you offload the administrative burdens of operating and scaling a distributed database, so that you don't have to worry about hardware provisioning, setup and configuration, replication, software patching, or cluster scaling.
26//! 
27//! With DynamoDB, you can create database tables that can store and retrieve any amount of data, and serve any level of request traffic. You can scale up or scale down your tables' throughput capacity without downtime or performance degradation, and use the Amazon Web Services Management Console to monitor resource utilization and performance metrics.
28//! 
29//! DynamoDB automatically spreads the data and traffic for your tables over a sufficient number of servers to handle your throughput and storage requirements, while maintaining consistent and fast performance. All of your data is stored on solid state disks (SSDs) and automatically replicated across multiple Availability Zones in an Amazon Web Services Region, providing built-in high availability and data durability.
30//! 
31//! ## Getting Started
32//! 
33//! > Examples are available for many services and operations, check out the
34//! > [usage examples](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/rustv1).
35//! 
36//! The SDK provides one crate per AWS service. You must add [Tokio](https://crates.io/crates/tokio)
37//! as a dependency within your Rust project to execute asynchronous code. To add `aws-sdk-dynamodb` to
38//! your project, add the following to your **Cargo.toml** file:
39//! 
40//! ```toml
41//! [dependencies]
42//! aws-config = { version = "1.1.7", features = ["behavior-version-latest"] }
43//! aws-sdk-dynamodb = "0.0.0-local"
44//! tokio = { version = "1", features = ["full"] }
45//! ```
46//! 
47//! Then in code, a client can be created with the following:
48//! 
49//! ```rust,no_run
50//! use aws_sdk_dynamodb as dynamodb;
51//! 
52//! #[::tokio::main]
53//! async fn main() -> Result<(), dynamodb::Error> {
54//!     let config = aws_config::load_from_env().await;
55//!     let client = aws_sdk_dynamodb::Client::new(&config);
56//! 
57//!     // ... make some calls with the client
58//! 
59//!     Ok(())
60//! }
61//! ```
62//! 
63//! See the [client documentation](https://docs.rs/aws-sdk-dynamodb/latest/aws_sdk_dynamodb/client/struct.Client.html)
64//! for information on what calls can be made, and the inputs and outputs for each of those calls.
65//! 
66//! ## Using the SDK
67//! 
68//! Until the SDK is released, we will be adding information about using the SDK to the
69//! [Developer Guide](https://docs.aws.amazon.com/sdk-for-rust/latest/dg/welcome.html). Feel free to suggest
70//! additional sections for the guide by opening an issue and describing what you are trying to do.

80//! # Crate Organization
81//! 
82//! The entry point for most customers will be [`Client`], which exposes one method for each API
83//! offered by Amazon DynamoDB. The return value of each of these methods is a "fluent builder",
84//! where the different inputs for that API are added by builder-style function call chaining,
85//! followed by calling `send()` to get a [`Future`](std::future::Future) that will result in
86//! either a successful output or a [`SdkError`](crate::error::SdkError).
87//! 
88//! Some of these API inputs may be structs or enums to provide more complex structured information.
89//! These structs and enums live in [`types`](crate::types). There are some simpler types for
90//! representing data such as date times or binary blobs that live in [`primitives`](crate::primitives).
91//! 
92//! All types required to configure a client via the [`Config`](crate::Config) struct live
93//! in [`config`](crate::config).
94//! 
95//! The [`operation`](crate::operation) module has a submodule for every API, and in each submodule
96//! is the input, output, and error type for that API, as well as builders to construct each of those.
97//! 
98//! There is a top-level [`Error`](crate::Error) type that encompasses all the errors that the
99//! client can return. Any other error type can be converted to this `Error` type via the
100//! [`From`](std::convert::From) trait.
101//! 
102//! The other modules within this crate are not required for normal usage.

111/// Client for calling Amazon DynamoDB.
112/// ## Constructing a `Client`
113/// 
114/// A [`Config`] is required to construct a client. For most use cases, the [`aws-config`]
115/// crate should be used to automatically resolve this config using
116/// [`aws_config::load_from_env()`], since this will resolve an [`SdkConfig`] which can be shared
117/// across multiple different AWS SDK clients. This config resolution process can be customized
118/// by calling [`aws_config::from_env()`] instead, which returns a [`ConfigLoader`] that uses
119/// the [builder pattern] to customize the default config.
120/// 
121/// In the simplest case, creating a client looks as follows:
122/// ```rust,no_run
123/// # async fn wrapper() {
124/// let config = aws_config::load_from_env().await;
125/// let client = aws_sdk_dynamodb::Client::new(&config);
126/// # }
127/// ```
128/// 
129/// Occasionally, SDKs may have additional service-specific values that can be set on the [`Config`] that
130/// is absent from [`SdkConfig`], or slightly different settings for a specific client may be desired.
131/// The [`Builder`](crate::config::Builder) struct implements `From<&SdkConfig>`, so setting these specific settings can be
132/// done as follows:
133/// 
134/// ```rust,no_run
135/// # async fn wrapper() {
136/// let sdk_config = ::aws_config::load_from_env().await;
137/// let config = aws_sdk_dynamodb::config::Builder::from(&sdk_config)
138/// # /*
139///     .some_service_specific_setting("value")
140/// # */
141///     .build();
142/// # }
143/// ```
144/// 
145/// See the [`aws-config` docs] and [`Config`] for more information on customizing configuration.
146/// 
147/// _Note:_ Client construction is expensive due to connection thread pool initialization, and should
148/// be done once at application start-up.

158/// # Using the `Client`
159/// 
160/// A client has a function for every operation that can be performed by the service.
161/// For example, the [`BatchExecuteStatement`](crate::operation::batch_execute_statement) operation has
162/// a [`Client::batch_execute_statement`], function which returns a builder for that operation.
163/// The fluent builder ultimately has a `send()` function that returns an async future that
164/// returns a result, as illustrated below:
165/// 
166/// ```rust,ignore
167/// let result = client.batch_execute_statement()
168///     .return_consumed_capacity("example")
169///     .send()
170///     .await;
171/// ```
172/// 
173/// The underlying HTTP requests that get made by this can be modified with the `customize_operation`
174/// function on the fluent builder. See the [`customize`](crate::client::customize) module for more
175/// information.
176/// # Waiters
177/// 
178/// This client provides `wait_until` methods behind the [`Waiters`](crate::client::Waiters) trait.
179/// To use them, simply import the trait, and then call one of the `wait_until` methods. This will
180/// return a waiter fluent builder that takes various parameters, which are documented on the builder
181/// type. Once parameters have been provided, the `wait` method can be called to initiate waiting.
182/// 
183/// For example, if there was a `wait_until_thing` method, it could look like:
184/// ```rust,ignore
185/// let result = client.wait_until_thing()
186///     .thing_id("someId")
187///     .wait(Duration::from_secs(120))
188///     .await;
189/// ```
