# AdotLayerVersion

An ADOT Lambda layer version that's specific to a lambda layer type and an architecture.

**Note:** These resolve to the legacy ADOT Lambda layers with an embedded collector.
For the recommended optimized layers, use `LayerVersion.fromLayerVersionArn()` with
an `AWSOpenTelemetryDistro*` layer ARN instead.

import {
  AdotLambdaExecWrapper,
  AdotLayerVersion,
  AdotLambdaLayerJavaScriptSdkVersion,
} from 'aws-cdk-lib/aws-lambda';

const fn = new lambda.Function(this, 'MyFunction', {
  runtime: lambda.Runtime.NODEJS_LATEST,
  handler: 'index.handler',
  code: lambda.Code.fromInline('exports.handler = function(event, ctx, cb) { return cb(null, "hi"); }'),
  adotInstrumentation: {
    layerVersion: AdotLayerVersion.fromJavaScriptSdkLayerVersion(AdotLambdaLayerJavaScriptSdkVersion.LATEST),
    execWrapper: AdotLambdaExecWrapper.REGULAR_HANDLER,
  },
});
```

## Initializer

```ts
new AdotLayerVersion()
```
