This code snippet appears to be written in **HashiCorp Configuration...

This code snippet appears to be written in HashiCorp Configuration Language (HCL), commonly used for Terraform configurations.

Explanation:

1. streams Output: The code creates a map (similar to a dictionary in many programming languages) and assigns it to the variable streams.

2. for Expression: The for expression iterates over the var.streams list (or map), which is assumed to be a variable defined elsewhere in the Terraform configuration.

3. Map Construction: Each element from var.streams (assumed to be iterable) is used to construct key-value pairs:

   • Key (stream.name): The name attribute of each stream object in var.streams becomes the key.
   • Value (stream): The entire stream object is used as the value.

4. Result (stream.name => stream):

   • You create a new map where each key is the name of a stream (from the input var.streams) and the corresponding value is the full stream object.

Final Summary:

The code transforms a list (or object) var.streams into a map, mapping each stream's name attribute to the entire stream object.

For example, if var.streams is:

[
  { name = "alpha", url = "http://alpha.example.com" },
  { name = "beta", url = "http://beta.example.com" }
]

The resulting streams map would be:

{
  "alpha" = { name = "alpha", url = "http://alpha.example.com" },
  "beta"  = { name = "beta", url = "http://beta.example.com" }
}
