20//! A load balancer can distribute incoming traffic across your EC2 instances. This enables you to increase the availability of your application. The load balancer also monitors the health of its registered instances and ensures that it routes traffic only to healthy instances. You configure your load balancer to accept incoming traffic by specifying one or more listeners, which are configured with a protocol and port number for connections from clients to the load balancer and a protocol and port number for connections from the load balancer to the instances.
21//!
22//! Elastic Load Balancing supports three types of load balancers: Application Load Balancers, Network Load Balancers, and Classic Load Balancers. You can select a load balancer based on your application needs. For more information, see the [Elastic Load Balancing User Guide](https://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/).
23//!
24//! This reference covers the 2012-06-01 API, which supports Classic Load Balancers. The 2015-12-01 API supports Application Load Balancers and Network Load Balancers.
25//!
26//! To get started, create a load balancer with one or more listeners using CreateLoadBalancer. Register your instances with the load balancer using RegisterInstancesWithLoadBalancer.
27//!
28//! All Elastic Load Balancing operations are _idempotent_, which means that they complete at most one time. If you repeat an operation, it succeeds with a 200 OK response code.
29//!
30//! ## Getting Started
31//!
32//! > Examples are available for many services and operations, check out the
33//! > [examples folder in GitHub](https://github.com/awslabs/aws-sdk-rust/tree/main/examples).
34//!
35//! The SDK provides one crate per AWS service. You must add [Tokio](https://crates.io/crates/tokio)
36//! as a dependency within your Rust project to execute asynchronous code. To add `aws-sdk-elasticloadbalancing` to
37//! your project, add the following to your **Cargo.toml** file:
38//!
39//! ```toml
40//! [dependencies]
41//! aws-config = { version = "1.1.7", features = ["behavior-version-latest"] }
42//! aws-sdk-elasticloadbalancing = "1.62.0"
43//! tokio = { version = "1", features = ["full"] }
44//! ```
45//!
46//! Then in code, a client can be created with the following:
47//!
48//! ```rust,no_run
49//! use aws_sdk_elasticloadbalancing as elasticloadbalancing;
50//!
51//! #[::tokio::main]
52//! async fn main() -> Result<(), elasticloadbalancing::Error> {
53//! let config = aws_config::load_from_env().await;
54//! let client = aws_sdk_elasticloadbalancing::Client::new(&config);
55//!
56//! // ... make some calls with the client
57//!
58//! Ok(())
59//! }
60//! ```
61//!
62//! See the [client documentation](https://docs.rs/aws-sdk-elasticloadbalancing/latest/aws_sdk_elasticloadbalancing/client/struct.Client.html)
63//! for information on what calls can be made, and the inputs and outputs for each of those calls.
64//!
65//! ## Using the SDK
66//!
67//! Until the SDK is released, we will be adding information about using the SDK to the
68//! [Developer Guide](https://docs.aws.amazon.com/sdk-for-rust/latest/dg/welcome.html). Feel free to suggest
69//! additional sections for the guide by opening an issue and describing what you are trying to do.

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

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

156/// # Using the `Client`
157///
158/// A client has a function for every operation that can be performed by the service.
159/// For example, the [`ApplySecurityGroupsToLoadBalancer`](crate::operation::apply_security_groups_to_load_balancer) operation has
160/// a [`Client::apply_security_groups_to_load_balancer`], function which returns a builder for that operation.
161/// The fluent builder ultimately has a `send()` function that returns an async future that
162/// returns a result, as illustrated below:
163///
164/// ```rust,ignore
165/// let result = client.apply_security_groups_to_load_balancer()
166/// .load_balancer_name("example")
167/// .send()
168/// .await;
169/// ```
170///
171/// The underlying HTTP requests that get made by this can be modified with the `customize_operation`
172/// function on the fluent builder. See the [`customize`](crate::client::customize) module for more
173/// information.
174/// # Waiters
175///
176/// This client provides `wait_until` methods behind the [`Waiters`](crate::client::Waiters) trait.
177/// To use them, simply import the trait, and then call one of the `wait_until` methods. This will
178/// return a waiter fluent builder that takes various parameters, which are documented on the builder
179/// type. Once parameters have been provided, the `wait` method can be called to initiate waiting.
180///
181/// For example, if there was a `wait_until_thing` method, it could look like:
182/// ```rust,ignore
183/// let result = client.wait_until_thing()
184/// .thing_id("someId")
185/// .wait(Duration::from_secs(120))
186/// .await;
187/// ```
