**CLAY_ID()** is used to generate and attach a [Clay_ElementId](#clay_elementid) to a layout element during declaration.
Note this macro only works with String literals and won't compile if used with a `char*` variable. To use a heap allocated `char*` string as an ID, use [CLAY_SID](#clay_sid).
To regenerate the same ID outside of layout declaration when using utility functions such as [Clay_PointerOver](#clay_pointerover), use the [Clay_GetElementId](#clay_getelementid) function.

### CLAY_SID()
`Clay_ElementId CLAY_SID(char *label)`
A version of [CLAY_ID](#clay_id) that can be used with heap allocated `char *` data. The underlying `char` data will not be copied internally and should live until at least the next frame.

### CLAY_IDI()
`Clay_ElementId CLAY_IDI(char *label, int32_t index)`
`Clay_ElementId CLAY_IDI(STRING_LITERAL label, int32_t index)`
An offset version of [CLAY_ID](#clay_id). Generates a [Clay_ElementId](#clay_elementid) string id from the provided `char *label`, combined with the `int index`. Used for generating ids for sequential elements (such as in a `for` loop) without having to construct dynamic strings at runtime.
