//! # gpt-forensic
//!
//! Forensic-grade GUID Partition Table (GPT) parser. A sibling to
//! [`mbr-forensic`](https://github.com/SecurityRonin/mbr-forensic): where that
//! crate parses the legacy MBR, this one parses the GPT that a protective MBR
//! advertises — validating the header and partition-array **CRC32** integrity,
//! reconciling the **primary and backup** GPT (divergence is a strong tampering
//! signal), and surfacing structural anomalies.
//!
//! Like its sibling, it is a pure `Read + Seek` library with no image-format
//! decoding of its own — compose it with the container crates (`ewf`, `vhd`,
//! `vmdk`, …) for E01/VHD/VMDK input.
