Struct CacheMetadata 

pub struct CacheMetadata {
    pub venv_path: String,
    pub requirements_file: Option<String>,
    pub requirements_hash: String,
    pub manifest_version: Option<String>,
    pub manifest_hash: Option<String>,
    pub python_version: Option<String>,
}

Cache metadata persisted next to each venv.

Field names match what client.py’s _save_cache_metadata writes, so metadata is interchangeable between the two implementations.

manifest_version and manifest_hash are Option to distinguish “absent” (older metadata, no signal) from “present and different” (a real change). That distinction is the whole point — see the module docs.

Fields

venv_path: String

Absolute path of the venv this metadata describes.

requirements_file: Option<String>

Absolute path of the requirements file, when there was one.

requirements_hash: String

SHA256 of the requirements file content (empty-content digest when there is no file).

manifest_version: Option<String>

Manifest version at install time. Absent in metadata written before this signal existed.

manifest_hash: Option<String>

SHA256 of the persisted manifest content. Absent in older metadata.

python_version: Option<String>

Interpreter version the venv was built with, for diagnostics.
