21//! AppConfig Data provides the data plane APIs your application uses to retrieve configuration data. Here's how it works:
22//!
23//! Your application retrieves configuration data by first establishing a configuration session using the AppConfig Data StartConfigurationSession API action. Your session's client then makes periodic calls to GetLatestConfiguration to check for and retrieve the latest data available.
24//!
25//! When calling StartConfigurationSession, your code sends the following information:
26//! - Identifiers (ID or name) of an AppConfig application, environment, and configuration profile that the session tracks.
27//! - (Optional) The minimum amount of time the session's client must wait between calls to GetLatestConfiguration.
28//!
29//! In response, AppConfig provides an InitialConfigurationToken to be given to the session's client and used the first time it calls GetLatestConfiguration for that session.
30//!
31//! This token should only be used once in your first call to GetLatestConfiguration. You _must_ use the new token in the GetLatestConfiguration response (NextPollConfigurationToken) in each subsequent call to GetLatestConfiguration.
32//!
33//! When calling GetLatestConfiguration, your client code sends the most recent ConfigurationToken value it has and receives in response:
34//! - NextPollConfigurationToken: the ConfigurationToken value to use on the next call to GetLatestConfiguration.
35//! - NextPollIntervalInSeconds: the duration the client should wait before making its next call to GetLatestConfiguration. This duration may vary over the course of the session, so it should be used instead of the value sent on the StartConfigurationSession call.
36//! - The configuration: the latest data intended for the session. This may be empty if the client already has the latest version of the configuration.
37//!
38//! The InitialConfigurationToken and NextPollConfigurationToken should only be used once. To support long poll use cases, the tokens are valid for up to 24 hours. If a GetLatestConfiguration call uses an expired token, the system returns BadRequestException.
39//!
40//! For more information and to view example CLI commands that show how to retrieve a configuration using the AppConfig Data StartConfigurationSession and GetLatestConfiguration API actions, see [Retrieving the configuration](http://docs.aws.amazon.com/appconfig/latest/userguide/appconfig-retrieving-the-configuration) in the _AppConfig User Guide_.
41//!
42//! ## Getting Started
43//!
44//! > Examples are available for many services and operations, check out the
45//! > [examples folder in GitHub](https://github.com/awslabs/aws-sdk-rust/tree/main/examples).
46//!
47//! The SDK provides one crate per AWS service. You must add [Tokio](https://crates.io/crates/tokio)
48//! as a dependency within your Rust project to execute asynchronous code. To add `aws-sdk-appconfigdata` to
49//! your project, add the following to your **Cargo.toml** file:
50//!
51//! ```toml
52//! [dependencies]
53//! aws-config = { version = "1.1.7", features = ["behavior-version-latest"] }
54//! aws-sdk-appconfigdata = "1.80.0"
55//! tokio = { version = "1", features = ["full"] }
56//! ```
57//!
58//! Then in code, a client can be created with the following:
59//!
60//! ```rust,no_run
61//! use aws_sdk_appconfigdata as appconfigdata;
62//!
63//! #[::tokio::main]
64//! async fn main() -> Result<(), appconfigdata::Error> {
65//! let config = aws_config::load_from_env().await;
66//! let client = aws_sdk_appconfigdata::Client::new(&config);
67//!
68//! // ... make some calls with the client
69//!
70//! Ok(())
71//! }
72//! ```
73//!
74//! See the [client documentation](https://docs.rs/aws-sdk-appconfigdata/latest/aws_sdk_appconfigdata/client/struct.Client.html)
75//! for information on what calls can be made, and the inputs and outputs for each of those calls.
76//!
77//! ## Using the SDK
78//!
79//! Until the SDK is released, we will be adding information about using the SDK to the
80//! [Developer Guide](https://docs.aws.amazon.com/sdk-for-rust/latest/dg/welcome.html). Feel free to suggest
81//! additional sections for the guide by opening an issue and describing what you are trying to do.

91//! # Crate Organization
92//!
93//! The entry point for most customers will be [`Client`], which exposes one method for each API
94//! offered by AWS AppConfig Data. The return value of each of these methods is a "fluent builder",
95//! where the different inputs for that API are added by builder-style function call chaining,
96//! followed by calling `send()` to get a [`Future`](std::future::Future) that will result in
97//! either a successful output or a [`SdkError`](crate::error::SdkError).
98//!
99//! Some of these API inputs may be structs or enums to provide more complex structured information.
100//! These structs and enums live in [`types`](crate::types). There are some simpler types for
101//! representing data such as date times or binary blobs that live in [`primitives`](crate::primitives).
102//!
103//! All types required to configure a client via the [`Config`](crate::Config) struct live
104//! in [`config`](crate::config).
105//!
106//! The [`operation`](crate::operation) module has a submodule for every API, and in each submodule
107//! is the input, output, and error type for that API, as well as builders to construct each of those.
108//!
109//! There is a top-level [`Error`](crate::Error) type that encompasses all the errors that the
110//! client can return. Any other error type can be converted to this `Error` type via the
111//! [`From`](std::convert::From) trait.
112//!
113//! The other modules within this crate are not required for normal usage.

121/// Client for calling AWS AppConfig Data.
122/// ## Constructing a `Client`
123///
124/// A [`Config`] is required to construct a client. For most use cases, the [`aws-config`]
125/// crate should be used to automatically resolve this config using
126/// [`aws_config::load_from_env()`], since this will resolve an [`SdkConfig`] which can be shared
127/// across multiple different AWS SDK clients. This config resolution process can be customized
128/// by calling [`aws_config::from_env()`] instead, which returns a [`ConfigLoader`] that uses
129/// the [builder pattern] to customize the default config.
130///
131/// In the simplest case, creating a client looks as follows:
132/// ```rust,no_run
133/// # async fn wrapper() {
134/// let config = aws_config::load_from_env().await;
135/// let client = aws_sdk_appconfigdata::Client::new(&config);
136/// # }
137/// ```
138///
139/// Occasionally, SDKs may have additional service-specific values that can be set on the [`Config`] that
140/// is absent from [`SdkConfig`], or slightly different settings for a specific client may be desired.
141/// The [`Builder`](crate::config::Builder) struct implements `From<&SdkConfig>`, so setting these specific settings can be
142/// done as follows:
143///
144/// ```rust,no_run
145/// # async fn wrapper() {
146/// let sdk_config = ::aws_config::load_from_env().await;
147/// let config = aws_sdk_appconfigdata::config::Builder::from(&sdk_config)
148/// # /*
149/// .some_service_specific_setting("value")
150/// # */
151/// .build();
152/// # }
153/// ```
154///
155/// See the [`aws-config` docs] and [`Config`] for more information on customizing configuration.
156///
157/// _Note:_ Client construction is expensive due to connection thread pool initialization, and should
158/// be done once at application start-up.

168/// # Using the `Client`
169///
170/// A client has a function for every operation that can be performed by the service.
171/// For example, the [`GetLatestConfiguration`](crate::operation::get_latest_configuration) operation has
172/// a [`Client::get_latest_configuration`], function which returns a builder for that operation.
173/// The fluent builder ultimately has a `send()` function that returns an async future that
174/// returns a result, as illustrated below:
175///
176/// ```rust,ignore
177/// let result = client.get_latest_configuration()
178/// .configuration_token("example")
179/// .send()
180/// .await;
181/// ```
182///
183/// The underlying HTTP requests that get made by this can be modified with the `customize_operation`
184/// function on the fluent builder. See the [`customize`](crate::client::customize) module for more
185/// information.
