Struct BlankNodeIdMapper

pub struct BlankNodeIdMapper { /* private fields */ }

Expand description

Canonically renames blank node identifiers in encounter order.

The first blank node seen gets _:b0, the second _:b1, and so on. Mapping is idempotent: mapping the same original ID twice returns the same canonical name.

Implementations§

Source §

impl BlankNodeIdMapper

Source

pub fn new() -> Self

Create a new, empty mapper.

Source

pub fn map(&mut self, original: &str) -> String

Map original to a canonical blank-node ID.

If original has been seen before the previously assigned name is returned (idempotent). Otherwise a new _:bN name is assigned.

Source

pub fn reset(&mut self)

Reset the mapper so it starts again from _:b0.

All previous mappings are discarded.
