pub fn bundled_runtime_cache_path() -> Option<PathBuf>Expand description
The runtime cache segment a bundle ships, read-only. cn export warms it
with the shader binaries a first launch would otherwise compile; because
those artifacts are backend IR (DXBC / SPIR-V) rather than machine code, one
warmed at package time is valid on any machine.
Resolves against the content root, so it stays readable on a read-only
install. That is also the only layout where this differs from
runtime_cache_path: a bundle the player can write to has one segment
serving both roles.
