optic-file

File I/O and cached-path resolution for the Optic engine.

Provides cached_path() to locate asset files relative to the executable or the OPTIC_ASSETS environment variable, and read_bytes() / write_bytes() for sanitised file operations.

use optic_file::{cached_path, read_bytes};

let path = cached_path("textures/wood.png", "otxtr");
let data = read_bytes(&path)?;
