How can I offset my equation numberings from the right margin by some amount?

I wish to align my equation number[ing]s to some arbitrary position offset from the right margin of the page by a specified amount, also using a custom format, eg “|1”. I first assumed I would be able to feed a #box of a certain width and with the desired numbering format as the content of it to my math.equation #set function like so:

#set math.equation(numbering:[#box(width:1.5cm,"|1")])

However, I found that the numbering named argument only accepts strings, not content.

I do not yet have enough experience with Typst scripting to see how to achieve this or, what’s more important, if this is at all possible given the current version of Typst. Therefore, kindly asking for suggestions and help with getting the functionality sought.

Regards

P.S. I imagine, if it exists, the way to achieving the above might also make possible the setting of all the other flavours of numberings, numeric or otherwise.

Numbering can also take a function which can include arbitrary content, so you can do as follows:

#set math.equation(numbering: n => box(width: 1.5cm)[|#n])
$ x := sqrt(5) $

Won’t this also affect the numbering when referencing the equation? Is there a good way to modify the one and the other separately

Depending on the result you want, you can either use a different approach to the original issue:

#outline(target: math.equation)

#set math.equation(numbering: "|1")
#show math.equation.where(block: true): set block(inset: (right: 1.5cm))
$ x := sqrt(5) $

This will not left-align all the numberings (like a constant-width numbering box would) but instead inset the numberings from the right.

Another approach would be using the state-outline trick described in another answer.
