pub fn board_scopes(
mirror: &Mirror,
targets: &Targets,
) -> Result<(Vec<Scope>, Vec<String>)>Expand description
The card scopes to keep current: every referenced board the mirror can resolve, and every other board whose cards are held and that its owner still lists.
A held board its owner no longer lists — deleted, or of an organisation this person left — is not wanted, and is forgotten with its cards.
