tile_stream — DRIVE inf op

• Data kinds: table × table → table

• Call: import fullseye as fs; fs.ledger.tile_stream(cache: 'dict', i: 'int', j: 'int', tp: 'dict', radius: 'int' = 1, step: 'float' = 10.0) -> 'dict' (to call the implementation directly, import driveinf; driveinf.tile_stream(cache: 'dict', i: 'int', j: 'int', tp: 'dict', radius: 'int' = 1, step: 'float' = 10.0) -> 'dict'; from the registry, opsdrive.get("tile_stream"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

車のいる区画 (i, j) の周り (2·radius + 1)² 区画を持ち、外れた区画を捨てる(`cache` をその場で書き換える)。

返り値 `{"loaded": [(i, j)], "evicted": [(i, j)], "n": 持っている区画の数}`。
