22//! You can use Amazon CloudWatch Logs to monitor, store, and access your log files from EC2 instances, CloudTrail, and other sources. You can then retrieve the associated log data from CloudWatch Logs using the CloudWatch console. Alternatively, you can use CloudWatch Logs commands in the Amazon Web Services CLI, CloudWatch Logs API, or CloudWatch Logs SDK.
23//!
24//! You can use CloudWatch Logs to:
25//! - __Monitor logs from EC2 instances in real time__: You can use CloudWatch Logs to monitor applications and systems using log data. For example, CloudWatch Logs can track the number of errors that occur in your application logs. Then, it can send you a notification whenever the rate of errors exceeds a threshold that you specify. CloudWatch Logs uses your log data for monitoring so no code changes are required. For example, you can monitor application logs for specific literal terms (such as "NullReferenceException"). You can also count the number of occurrences of a literal term at a particular position in log data (such as "404" status codes in an Apache access log). When the term you are searching for is found, CloudWatch Logs reports the data to a CloudWatch metric that you specify.
26//! - __Monitor CloudTrail logged events__: You can create alarms in CloudWatch and receive notifications of particular API activity as captured by CloudTrail. You can use the notification to perform troubleshooting.
27//! - __Archive log data__: You can use CloudWatch Logs to store your log data in highly durable storage. You can change the log retention setting so that any log events earlier than this setting are automatically deleted. The CloudWatch Logs agent helps to quickly send both rotated and non-rotated log data off of a host and into the log service. You can then access the raw log data when you need it.

29//! ## Getting Started
30//!
31//! > Examples are available for many services and operations, check out the
32//! > [usage examples](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/rustv1).
33//!
34//! The SDK provides one crate per AWS service. You must add [Tokio](https://crates.io/crates/tokio)
35//! as a dependency within your Rust project to execute asynchronous code. To add `aws-sdk-cloudwatchlogs` to
36//! your project, add the following to your **Cargo.toml** file:
37//!
38//! ```toml
39//! [dependencies]
40//! aws-config = { version = "1.1.7", features = ["behavior-version-latest"] }
41//! aws-sdk-cloudwatchlogs = "1.107.0"
42//! tokio = { version = "1", features = ["full"] }
43//! ```
44//!
45//! Then in code, a client can be created with the following:
46//!
47//! ```rust,no_run
48//! use aws_sdk_cloudwatchlogs as cloudwatchlogs;
49//!
50//! #[::tokio::main]
51//! async fn main() -> Result<(), cloudwatchlogs::Error> {
52//! let config = aws_config::load_from_env().await;
53//! let client = aws_sdk_cloudwatchlogs::Client::new(&config);
54//!
55//! // ... make some calls with the client
56//!
57//! Ok(())
58//! }
59//! ```
60//!
61//! See the [client documentation](https://docs.rs/aws-sdk-cloudwatchlogs/latest/aws_sdk_cloudwatchlogs/client/struct.Client.html)
62//! for information on what calls can be made, and the inputs and outputs for each of those calls.
63//!
64//! ## Using the SDK
65//!
66//! Until the SDK is released, we will be adding information about using the SDK to the
67//! [Developer Guide](https://docs.aws.amazon.com/sdk-for-rust/latest/dg/welcome.html). Feel free to suggest
68//! additional sections for the guide by opening an issue and describing what you are trying to do.

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

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

155/// # Using the `Client`
156///
157/// A client has a function for every operation that can be performed by the service.
158/// For example, the [`AssociateKmsKey`](crate::operation::associate_kms_key) operation has
159/// a [`Client::associate_kms_key`], function which returns a builder for that operation.
160/// The fluent builder ultimately has a `send()` function that returns an async future that
161/// returns a result, as illustrated below:
162///
163/// ```rust,ignore
164/// let result = client.associate_kms_key()
165/// .log_group_name("example")
166/// .send()
167/// .await;
168/// ```
169///
170/// The underlying HTTP requests that get made by this can be modified with the `customize_operation`
171/// function on the fluent builder. See the [`customize`](crate::client::customize) module for more
172/// information.
