pub fn save_blob_cache(path: &Path, cache: &BlobSchemaCache) -> Result<()>Expand description
Persist a blob-to-schema cache atomically.
Writes to <path>.tmp and renames into place, so a crash mid-write
cannot leave a partial file that would later parse as corrupt.
§Errors
Returns any I/O error encountered while creating parent directories, writing, or renaming.
