Struct chalk_solve::display::WriterState

source ·
pub struct WriterState<I, DB, P = DB>
where DB: RustIrDatabase<I> + ?Sized, P: Borrow<DB>, I: Interner,
{ pub(super) db: P, id_aliases: Arc<Mutex<IdAliases<I>>>, _phantom: PhantomData<DB>, }
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.

Implementations§

source§

impl<I, DB, P> WriterState<I, DB, P>
where DB: RustIrDatabase<I> + ?Sized, P: Borrow<DB>, I: Interner,

source

pub fn new(db: P) -> Self

source

pub(super) fn wrap_db_ref<'a, DB2, P2, F>( &'a self, f: F, ) -> WriterState<I, DB2, P2>
where DB2: RustIrDatabase<I> + ?Sized, P2: Borrow<DB2>, F: FnOnce(&'a P) -> P2,

Returns a new version of self containing a wrapped database which references the outer data.

f will be run on the internal database, and the returned result will wrap the result from f. For consistency, f should always contain the given database, and must keep the same ID<->item relationships.
