Struct WriterState 

Source 
pub struct WriterState<I, DB, P = DB>
where
    DB: RustIrDatabase<I> + ?Sized,
    P: Borrow<DB>,
    I: Interner,
{ /* private fields */ }
Expand description

Writer state which persists across multiple writes.

Currently, this means keeping track of what IDs have been given what names, including deduplication information.

This data is stored using interior mutability - clones will point to the same underlying data.

Uses a separate type, P, for the database stored inside to account for Arc or wrapping other storage mediums.
