pub struct ID(_);
Expand description
A unique per database face ID.
We’re using u32
internally, which is auto-incremented for each face.
A face removal doesn’t decrement the counter.
Since Database
is not global/unique, we cannot guarantee that a specific ID
is actually from the same db instance. This is up to the caller.
ID overflow will cause a panic, but it’s highly unlikely that someone would load more than 4 billion font faces.
