Implementations§

Source§

impl<'db, 'mt, 'l> Mapper<'db, 'mt, 'l>

Source

pub fn new( db: &'db dyn Database, variables: &'mt mut VariableArena<'db>, lowered: &'l Lowered<'db>, call_stmt: StatementCall<'db>, block_id_offset: usize, ) -> Self

Trait Implementations§

Source§

impl<'db, 'mt> Rebuilder<'db> for Mapper<'db, 'mt, '_>

Source§

fn map_var_id(&mut self, orig_var_id: VariableId) -> VariableId

Maps a var id from the original lowering representation to the equivalent id in the new lowering representation. If the variable wasn’t assigned an id yet, a new id is assigned.

Source§

fn map_block_id(&mut self, orig_block_id: BlockId) -> BlockId

Maps a block id from the original lowering representation to the equivalent id in the new lowering representation.

Source§

fn map_location(&mut self, location: LocationId<'db>) -> LocationId<'db>

Adds the inlining location to a location.
