Module media_kinds 

Central registry of supported media extensions, MIME types, and asset kinds.

All file-extension lookups in the upload, watch, and library-view paths resolve through this module so the three previously hand-maintained tables cannot drift apart.

Enums

AssetKind

Discriminant representing whether a media file is an image or a video.

Statics

MIME_BY_EXT 🔒

Compile-time mapping from lowercased file extensions to standard MIME types.

RAW_EXTENSIONS

Camera RAW extensions – subset of SUPPORTED that needs RAW-specific decoding (libraw) instead of pixbuf or image-rs.

SUPPORTED

Static set of all supported file extensions for quick membership lookups. Mirrors Immich’s server-accepted formats; MPO is intentionally excluded.

Functions

asset_kind

Determine the media kind based on the prefix of the MIME type.

extension_lower 🔒

Extract the extension from a path and return it lowercased.

is_raw_ext

Whether the extension is a camera RAW format.

is_raw_path

Whether the path’s extension is a camera RAW format.

is_supported_ext

Check if a lowercased extension is present in the supported set.

is_supported_path

Lowercase the path’s extension and return whether it is an accepted media file.

is_video_path

Whether the path’s extension maps to a video MIME type.

mime_for

MIME type for a known extension (already lowercased).

mime_for_path

MIME type for any path; falls back to application/octet-stream for unknowns.
