Rust crate fat_fs_types

Low-level #![no_std] helper library for accessing Microsoft's FAT12/16/32 and exFAT file systems. Only defines constants, types and some very simple functions.

You will want to use one of the features zerocopy or bytemuck (together with the respective crate).

A lot of the structs in here only implement Copy if you have feature = "bytemuck" enabled since some of them are quite large. All #[repr(C)] structs with public fields have a stable layout, no padding and an alignment of 1.
