| # `tomap` Function |
| |
| `tomap` converts its argument to a map value. |
| |
| Explicit type conversions are rarely necessary in Terraform because it will |
| convert types automatically where required. Use the explicit type conversion |
| functions only to normalize types returned in module outputs. |
| |
| ## Examples |
| |
| ``` |
| > tomap({"a" = 1, "b" = 2}) |
| { |
| "a" = 1 |
| "b" = 2 |
| } |
| ``` |
| |
| Since Terraform's concept of a map requires all of the elements to be of the |
| same type, mixed-typed elements will be converted to the most general type: |
| |
| ``` |
| > tomap({"a" = "foo", "b" = true}) |
| { |
| "a" = "foo" |
| "b" = "true" |
| } |
| ``` |
