Struct osm_io::osm::apidb_dump::read::reader::Reader

pub struct Reader { /* private fields */ }

Reader of apidb schema dump produced by pg_dump

Implementations

impl Reader

pub fn new(input_path: PathBuf, tmp_path: PathBuf) -> Result<Reader, Error>

Create a new Reader

• input_path - a path to directory that contains apidb schema dump produced by pg_dump with directory format. For example:

 pg_dump --host localhost --port 5432 --username openstreetmap --no-password --file /result --format d -d openstreetmap --compress 0 --table public.nodes --table public.node_tags --table public.ways --table public.way_nodes --table public.way_tags --table public.relations --table public.relation_members --table public.relation_tags --table public.changesets --table public.users

The input is sorted using primary keys for each table found in input_path/toc.dat which may take significant time depending on the size of the input

• tmp_path - location used by the sorting algorithm for intermediate and final result. Should have space for at least 2.2 * input size

pub fn elements(&self) -> Result<ElementIterator, Error>

Create iterator over the elements.

The behaviour is similar to that of [osm::pbf::element_iterator::ElementIterator] with the distinction that [Element::Sentinel] is produced after completing each type, that is Node, Way, Relation.
