| # Accessing Fields | |
| Selectors access fields within a struct using the `.` notation. | |
| This only works if a field name is a valid identifier and it is not computed. | |
| For other cases one can use the indexing notation. | |
| <!-- CUE editor --> | |
| ``` | |
| a: { | |
| b: 2 | |
| "c-e": 5 | |
| } | |
| v: a.b | |
| w: a["c-e"] | |
| ``` | |
| <!-- result --> | |
| ``` | |
| a: { | |
| b: 2 | |
| } | |
| v: 2 | |
| w: 5 | |
| ``` |
