Which of these code styles do you find preferable?
First option using mut with constructor in the beginning:
let mut post_form = PostInsertForm::new(
data.name.trim().to_string(),
local_user_view.person.id,
data.community_id,
);
post_form.url = url.map(Into::into);
post_form.body = body;
post_form.alt_text = data.alt_text.clone();
post_form.nsfw = data.nsfw;
post_form.language_id = language_id;
Second option without mut and constructor at the end:
let post_form = PostInsertForm {
url: url.map(Into::into),
body,
alt_text: data.alt_text.clone(),
nsfw: data.nsfw,
language_id,
..PostInsertForm::new(
data.name.trim().to_string(),
local_user_view.person.id,
data.community_id,
)
};

Neither.
new()
give you a fully valid and usable struct value.Maybe you should also use substructs that hold some of the info.
We used to have TypedBuilder (which is builder pattern), but switched to DeriveNew, as its a bit cleaner, and requires less generated code.
