Google Cloud Functions is used to deploy functions that are executed by Google in response to various events. Data connected with that event is passed to a function as the input data. A **function** is a resource which describes a function that should be executed and how it is triggered.
Returns a function with the given name from the requested project.
Request for the `GetFunction` method.
Required. The name of the function which details should be obtained.
Optional. The optional version of the 1st gen function whose details should be obtained. The version of a 1st gen function is an integer that starts from 1 and gets incremented on redeployments. GCF may keep historical configs for old versions of 1st gen function. This field can be specified to fetch the historical configs. This field is valid only for GCF 1st gen function.
Returns a list of functions that belong to the requested project.
Request for the `ListFunctions` method.
Required. The project and location from which the function should be listed, specified in the format `projects/*/locations/*` If you want to list functions in all locations, use "-" in place of a location. When listing functions in all locations, if one or more location(s) are unreachable, the response will contain functions from all reachable locations along with the names of any unreachable locations.
Maximum number of functions to return per call. The largest allowed page_size is 1,000, if the page_size is omitted or specified as greater than 1,000 then it will be replaced as 1,000. The size of the list response can be less than specified when used with filters.
The value returned by the last `ListFunctionsResponse`; indicates that this is a continuation of a prior `ListFunctions` call, and that the system should return the next page of data.
The filter for Functions that match the filter expression, following the syntax outlined in https://google.aip.dev/160.
The sorting order of the resources returned. Value should be a comma separated list of fields. The default sorting oder is ascending. See https://google.aip.dev/132#ordering.
Response for the `ListFunctions` method.

Required. The name of the function which should be deleted.
Returns a signed URL for uploading a function source code. For more information about the signed URL usage see: https://cloud.google.com/storage/docs/access-control/signed-urls. Once the function source code upload is complete, the used signed URL should be provided in CreateFunction or UpdateFunction request as a reference to the function source code. When uploading source code to the generated signed URL, please follow these restrictions: * Source file type should be a zip file. * No credentials should be attached - the signed URLs provide access to the target bucket using internal service identity; if credentials were attached, the identity from the credentials would be used, but that identity does not have permissions to upload files to the URL. When making a HTTP PUT request, specify this header: * `content-type: application/zip` Do not specify this header: * `Authorization: Bearer YOUR_TOKEN`

Required. The project and location in which the Google Cloud Storage signed URL should be generated, specified in the format `projects/*/locations/*`.
[Preview] Resource name of a KMS crypto key (managed by the user) used to encrypt/decrypt function source code objects in intermediate Cloud Storage buckets. When you generate an upload url and upload your source code, it gets copied to an intermediate Cloud Storage bucket. The source code is then copied to a versioned directory in the sources bucket in the consumer project during the function deployment. It must match the pattern `projects/{project}/locations/{location}/keyRings/{key_ring}/cryptoKeys/{crypto_key}`. The Google Cloud Functions service account (service-{project_number}@gcf-admin-robot.iam.gserviceaccount.com) must be granted the role 'Cloud KMS CryptoKey Encrypter/Decrypter (roles/cloudkms.cryptoKeyEncrypterDecrypter)' on the Key/KeyRing/Project/Organization (least access preferred).

The number of CPUs used in a single container instance. Default value is calculated from available memory. Supports the same values as Cloud Run, see https://cloud.google.com/run/docs/reference/rest/v1/Container#resourcerequirements Example: "1" indicates 1 vCPU
Environment variables that shall be available during function execution.
The limit on the maximum number of function instances that may coexist at a given time. In some cases, such as rapid traffic surges, Cloud Functions may, for a short period of time, create more instances than the specified max instances limit. If your function cannot tolerate this temporary behavior, you may want to factor in a safety margin and set a lower max instances value than your function can tolerate. See the [Max Instances](https://cloud.google.com/functions/docs/max-instances) Guide for more details.
The limit on the minimum number of function instances that may coexist at a given time. Function instances are kept in idle state for a short period after they finished executing the request to reduce cold start time for subsequent requests. Setting a minimum instance count will ensure that the given number of instances are kept running in idle state always. This can help with cold start times when jump in incoming request count occurs after the idle instance would have been stopped in the default case.
