/**
 * Provides details about an AWS Lambda Layer Version. Use this data source to retrieve information about a specific layer version or find the latest version compatible with your runtime and architecture requirements.
 *
 * ## Example Usage
 *
 * ### Get Latest Layer Version
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as aws from "@pulumi/aws";
 *
 * const example = aws.lambda.getLayerVersion({
 *     layerName: "my-shared-utilities",
 * });
 * // Use the layer in a Lambda function
 * const exampleFunction = new aws.lambda.Function("example", {
 *     code: new pulumi.asset.FileArchive("function.zip"),
 *     name: "example_function",
 *     role: lambdaRole.arn,
 *     handler: "index.handler",
 *     runtime: aws.lambda.Runtime.NodeJS24dX,
 *     layers: [example.then(example => example.arn)],
 * });
 * ```
 *
 * ### Get Specific Layer Version
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as aws from "@pulumi/aws";
 *
 * const example = aws.lambda.getLayerVersion({
 *     layerName: "production-utilities",
 *     version: 5,
 * });
 * export const layerInfo = {
 *     arn: example.then(example => example.arn),
 *     version: example.then(example => example.version),
 *     description: example.then(example => example.description),
 * };
 * ```
 *
 * ### Get Latest Compatible Layer Version
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as aws from "@pulumi/aws";
 *
 * // Find latest layer version compatible with Python 3.12
 * const pythonLayer = aws.lambda.getLayerVersion({
 *     layerName: "python-dependencies",
 *     compatibleRuntime: "python3.12",
 * });
 * // Find latest layer version compatible with ARM64 architecture
 * const armLayer = aws.lambda.getLayerVersion({
 *     layerName: "optimized-libraries",
 *     compatibleArchitecture: "arm64",
 * });
 * // Use both layers in a function
 * const example = new aws.lambda.Function("example", {
 *     code: new pulumi.asset.FileArchive("function.zip"),
 *     name: "multi_layer_function",
 *     role: lambdaRole.arn,
 *     handler: "app.handler",
 *     runtime: aws.lambda.Runtime.Python3d12,
 *     architectures: ["arm64"],
 *     layers: [
 *         pythonLayer.then(pythonLayer => pythonLayer.arn),
 *         armLayer.then(armLayer => armLayer.arn),
 *     ],
 * });
 * ```
 *
 * ### Compare Layer Versions
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as aws from "@pulumi/aws";
 *
 * // Get latest version
 * const latest = aws.lambda.getLayerVersion({
 *     layerName: "shared-layer",
 * });
 * // Get specific version for comparison
 * const stable = aws.lambda.getLayerVersion({
 *     layerName: "shared-layer",
 *     version: 3,
 * });
 * const useLatestLayer = latest.then(latest => latest.version > 5);
 * const selectedLayer = useLatestLayer ? latest.then(latest => latest.arn) : stable.then(stable => stable.arn);
 * export const selectedLayerVersion = useLatestLayer ? latest.then(latest => latest.version) : stable.then(stable => stable.version);
 * ```
 *
 * ### Cross-Account Layer Access
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as aws from "@pulumi/aws";
 *
 * // Reference a layer from another AWS account using full ARN with version
 * const sharedLayer = aws.lambda.getLayerVersion({
 *     layerVersionArn: "arn:aws:lambda:us-east-1:123456789012:layer:shared-utilities:5",
 * });
 * // Use in your Lambda function
 * const example = new aws.lambda.Function("example", {
 *     code: new pulumi.asset.FileArchive("function.zip"),
 *     name: "cross_account_example",
 *     role: lambdaRole.arn,
 *     handler: "index.handler",
 *     runtime: aws.lambda.Runtime.NodeJS24dX,
 *     layers: [sharedLayer.then(sharedLayer => sharedLayer.arn)],
 * });
 * ```
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as aws from "@pulumi/aws";
 *
 * // Reference a layer ARN without version (requires ListLayerVersions permission)
 * const latestShared = aws.lambda.getLayerVersion({
 *     layerVersionArn: "arn:aws:lambda:us-east-1:123456789012:layer:shared-utilities",
 * });
 * ```
