lamexfat
A no_std read-only exFAT reader for UEFI bootloaders.
Early development. This repository establishes the build, license, CI, and the public API contract. The filesystem implementation is in progress and the crate is not yet functional — do not depend on it for production use.
Scope
lamexfat reads the exFAT on-disk format (boot region, FAT, cluster heap, directory entry set, up-case table) over a byte source, exposing a read-only volume a
bootloader can traverse to find a kernel and initramfs. Read-only by
construction. The motivating target is removable media — SD cards and USB sticks formatted exFAT.
Basis
It vendors the parsing core of exfat-slim (Apache-2.0) — a clean-room
reader, not GPL kernel/userspace source. See NOTICE for attribution.
