Enum FilenameEncoding 

#[non_exhaustive]
pub enum FilenameEncoding {
    Direct,
    UrlEncode,
    Base64,
}

File-naming encoding strategy for entity IDs.

Determines how entity IDs are encoded into filesystem-safe filenames.

Empty IDs are rejected by every strategy (they would produce a hidden dot-file invisible to list_ids).

Case-insensitive filesystems

All strategies produce case-sensitive filenames. On case-insensitive filesystems (macOS / Windows defaults), two IDs that differ only in case (Direct), or whose encoded forms differ only in case (Base64), map to the same file and silently overwrite each other.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Direct

Use the ID directly as the filename.

Only IDs consisting entirely of ASCII alphanumeric characters, -, and _ are accepted; any other character causes a StoreError::FilenameEncoding error.

UrlEncode

URL-encode the ID so that special characters become percent-escaped sequences that are safe to use in a filename.

Base64

Base64-encode the ID using the URL-safe alphabet without padding.
