dZ dS )CachedFileInfoa Frozen data structure holding information about a single cached file.
Args:
file_name (`str`):
Name of the file. Example: `config.json`.
file_path (`Path`):
Path of the file in the `snapshots` directory. The file path is a symlink
referring to a blob in the `blobs` folder.
blob_path (`Path`):
Path of the blob file. This is equivalent to `file_path.resolve()`.
size_on_disk (`int`):
Size of the blob file in bytes.
blob_last_accessed (`float`):
Timestamp of the last time the blob file has been accessed (from any
revision).
blob_last_modified (`float`):
Timestamp of the last time the blob file has been modified/created.
`blob_last_accessed` and `blob_last_modified` reliability can depend on the OS you
are using. See [python documentation](https://docs.python.org/3/library/os.html#os.stat_result)
for more details.

dZdS )CachedRevisionInfoaN Frozen data structure holding information about a revision.
A revision correspond to a folder in the `snapshots` folder and is populated with
the exact tree structure as the repo on the Hub but contains only symlinks. A
revision can be either referenced by 1 or more `refs` or be "detached" (no refs).
Args:
commit_hash (`str`):
Hash of the revision (unique).
Example: `"9338f7b671827df886678df2bdd7cc7b4f36dffd"`.
snapshot_path (`Path`):
Path to the revision directory in the `snapshots` folder. It contains the
exact tree structure as the repo on the Hub.
files: (`FrozenSet[CachedFileInfo]`):
Set of [`~CachedFileInfo`] describing all files contained in the snapshot.
refs (`FrozenSet[str]`):
Set of `refs` pointing to this revision. If the revision has no `refs`, it
is considered detached.
Example: `{"main", "2.4.0"}` or `{"refs/pr/1"}`.
size_on_disk (`int`):
Sum of the blob file sizes that are symlink-ed by the revision.
last_modified (`float`):
Timestamp of the last time the revision has been created/modified.
`last_accessed` cannot be determined correctly on a single revision as blob files
are shared across revisions.
`size_on_disk` is not necessarily the sum of all file sizes because of possible
duplicated files. Besides, only blobs are taken into account, not the (negligible)
size of folders and symlinks.

DeleteCacheStrategya Frozen data structure holding the strategy to delete cached revisions.
This object is not meant to be instantiated programmatically but to be returned by
[`~utils.HFCacheInfo.delete_revisions`]. See documentation for usage example.
Args:
expected_freed_size (`float`):
Expected freed size once strategy is executed.
blobs (`FrozenSet[Path]`):
Set of blob file paths to be deleted.
refs (`FrozenSet[Path]`):
Set of reference file paths to be deleted.

Set of snapshots to be deleted (directory of symlinks).

Zd S ) HFCacheInfoa Frozen data structure holding information about the entire cache-system.
This data structure is returned by [`scan_cache_dir`] and is immutable.
Args:
size_on_disk (`int`):
Sum of all valid repo sizes in the cache-system.
repos (`FrozenSet[CachedRepoInfo]`):
Set of [`~CachedRepoInfo`] describing all valid cached repos found on the
cache-system while scanning.
warnings (`List[CorruptedCacheException]`):
List of [`~CorruptedCacheException`] that occurred while scanning the cache.
Those exceptions are captured so that the scan can continue. Corrupted repos
are skipped from the scan.
Here `size_on_disk` is equal to the sum of all repo sizes (only blobs). However if
some cached repos are corrupted, their sizes are not taken into account.

dS )a Prepare the strategy to delete one or more revisions cached locally.
Input revisions can be any revision hash. If a revision hash is not found in the
local cache, a warning is thrown but no error is raised. Revisions can be from
different cached repos since hashes are unique across repos,
Examples:
```py
>>> from huggingface_hub import scan_cache_dir
>>> cache_info = scan_cache_dir()
>>> delete_strategy = cache_info.delete_revisions(
... "81fd1d6e7847c99f5862c9fb81387956d99ec7aa"
... )
>>> print(f"Will free {delete_strategy.expected_freed_size_str}.")
Will free 7.9K.
>>> delete_strategy.execute()
Cache deletion done. Saved 7.9K.
```
```py
>>> from huggingface_hub import scan_cache_dir
>>> scan_cache_dir().delete_revisions(
... "81fd1d6e7847c99f5862c9fb81387956d99ec7aa",
... "e2983b237dccf3ab4937c97fa717319a9ca1a96d",
... "6c0e6080953db56375760c0471a8c5f2929baf11",
... ).execute()
Cache deletion done. Saved 8.6G.
```
`delete_revisions` returns a [`~utils.DeleteCacheStrategy`] object that needs to
be executed. The [`~utils.DeleteCacheStrategy`] is not meant to be modified but
allows having a dry run before actually executing the deletion.

Use `scan_cache_dir` in order to programmatically scan your cache-system. The cache
will be scanned repo by repo. If a repo is corrupted, a [`~CorruptedCacheException`]
will be thrown internally but captured and returned in the [`~HFCacheInfo`]
structure. Only valid repos get a proper report.
```py
