Which code style to initialize structs?
Which code style to initialize structs?
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,
)
};

Definitely the second one.
- It avoids Mut
- It makes clear that the initialization is over at the end of of the statement. The first option invites people to change some more properties hundreds of lines down where you won't see them.
