Module multipart 

Shared multipart-body parsing helpers.

Provides parse_multipart — a generic drain over an axum::extract::Multipart stream that classifies each part as either an in-memory form field (≤ 4 KiB) or a spooled file written to a per-request temp directory.

Per-router validation (filename traversal checks, URL-body detection, extension checks, …) belongs in each router’s own parse adapter, not here.

Structs

MultipartOpts

Options that control multipart parsing.

ParsedForm

Result of a parse_multipart call.

SpooledFile

A single spooled-to-disk file part.

UploadGuard

RAII wrapper that removes the per-request spool directory on Drop.

Functions

check_filename_traversal

Check a filename for path traversal sequences.

parse_multipart

Drain an axum Multipart stream into a ParsedForm.

sanitize_path_component

Replace any filesystem-unsafe characters with _ and truncate to 200 chars.
