# runtime-abi
|
|
|
|
|
|
|
|
|
|
This crate has ABI functions (like syscalls) and extensions to the runtime for enabling ABIs (e.g. virtual filesystem).
|
|
|
|
|
|
|
|
|
|
## Virtual Filesystem (experimental)
|
|
|
|
|
|
|
|
|
|
The virtual filesystem allows the runtime to read bundled wasm data as if they were files. Data that is stored in a
|
|
|
|
|
custom section compressed with [zstd][1] compression and archived with [tar][2] will be exposed as files and mounted
|
|
|
|
|
in the `/` root.
|
|
|
|
|
|
|
|
|
|
The only current supported operation is the `read` syscall.
|
|
|
|
|
|
|
|
|
|
The virtual filesystem is not enabled by default. Build with `--features vfs` to use it.

[Zbox][3] is a virtual filesystem that depends on [libsodium][4]. See [installation instructions][5] for libsodium here. One can
|
|
|
|
|
statically link libsodium with the [instructions][6] on Zbox's readme.
