Datatype::parse recurses into itself for Compound/Enumeration/ VariableLength/Array/Complex member and base types with no depth counter. A message data size capped at u16::MAX (65535 bytes) allows ~8000 levels of nesting in a crafted file, enough to blow the stack — worse on the project's no_std/embedded targets with only a few KB of stack. Thread a depth counter through a new parse_with_depth, mirroring object_header.rs's continuation-depth guard, and reject past 64 levels with FormatError::NestingDepthExceeded. The public Datatype::parse signature is unchanged. INT-03
clawhdf5-format
Pure-Rust HDF5 binary format parsing and writing — no C dependencies.
Features
- Zero-copy superblock, object header, and B-tree parsing
- Chunked dataset read/write with filter pipelines
no_stdsupport (disablestdfeature)- Optional parallel reads via Rayon
- SHA-256 provenance tracking
Usage
use clawhdf5_format::Superblock;
let data = std::fs::read("data.h5").unwrap();
let sb = Superblock::from_bytes(&data).unwrap();
println!("HDF5 version {}.{}", sb.version_major(), sb.version_minor());
