Flat Filesystem
A simple way to package a small number of files into a single flat memory area. Like CPIO. [no-std]
Same reason why CPIO exists. I needed a way to easily create read-only partitions in Rust in 2023, and could not find a suitable and lightweight way to do it, so I rolled my own.
- [no-std]
- pack a small (~1k) number of "files" into a single contiguous memory region
- here a "file" is a pair of (&str, &[u8])
- unpack that memory region back into "files"
- expose the "files" as a rudimentary directory tree (readonly)
- the "unpacked" filesystem should be reasonably efficient (both memory and CPU)
- no panicking (other than on OOM)
- neither packing nor unpacking are required to be especially fast
- ensuring that filenames are "canonical" in any sense is not a goal
- for example, the user may add a "/foo" file and a "/foo/bar" file, resulting in the root directory containing both a "foo" file and a "foo" directory
