dcm-dump

dcm-dump is a minimal Rust toolkit for inspecting DICOM files without any external dependencies.

Current capabilities:

• read the 128-byte preamble and four-byte DICM prefix
• detect the transfer syntax UID from the File Meta Information group

Near-term goals:

• parse individual data elements (starting with Explicit VR Little Endian)
• validate common tags against the DICOM dictionary
• surface human-readable previews for textual values and concise hex dumps for binary payloads
• flag malformed elements (unexpected lengths, missing delimiters, etc.)

Longer-term stretch ideas:

• graceful handling of sequences and undefined-length items
• configurable output formats (plain text, JSON, or CSV summaries)
• optional heuristics to spot anonymisation issues or missing required attributes

This crate is intended both as a simple CLI and as a reusable library module, so everything is kept dependency-free and straightforward to read.
