Using getFunctions

Two invocation forms are available. The direct form accepts plain arguments and either blocks until the result value is available, or returns a Promise-wrapped result. The output form accepts Input-wrapped arguments and returns an Output-wrapped result.

function getFunctions(args: GetFunctionsArgs, opts?: InvokeOptions): Promise<GetFunctionsResult>
function getFunctionsOutput(args: GetFunctionsOutputArgs, opts?: InvokeOptions): Output<GetFunctionsResult>

def get_functions(region: Optional[str] = None,
                  opts: Optional[InvokeOptions] = None) -> GetFunctionsResult
def get_functions_output(region: Optional[pulumi.Input[str]] = None,
                  opts: Optional[InvokeOptions] = None) -> Output[GetFunctionsResult]

func GetFunctions(ctx *Context, args *GetFunctionsArgs, opts ...InvokeOption) (*GetFunctionsResult, error)
func GetFunctionsOutput(ctx *Context, args *GetFunctionsOutputArgs, opts ...InvokeOption) GetFunctionsResultOutput

> Note: This function is named GetFunctions in the Go SDK.

public static class GetFunctions 
{
    public static Task<GetFunctionsResult> InvokeAsync(GetFunctionsArgs args, InvokeOptions? opts = null)
    public static Output<GetFunctionsResult> Invoke(GetFunctionsInvokeArgs args, InvokeOptions? opts = null)
}

public static CompletableFuture<GetFunctionsResult> getFunctions(GetFunctionsArgs args, InvokeOptions options)
public static Output<GetFunctionsResult> getFunctions(GetFunctionsArgs args, InvokeOptions options)
