Overview ¶
sysfs is a almost verbatim copy of internal package sysfs from wazero. As it's internal, it cannot be used outside of wazero; however, it's useful to be able to create AdaptFS and SysFS and instrument them and experiment on them further.
Do NOT use it in prod code, because it is not being kept up-to-date with wazero; use it only for experimenting/debugging.
Network and polling was removed, as it was dependent on other internal packages. As was all testing.
path.go is copied over from internal platform package.
Original wazero docs:
Package sysfs includes a low-level filesystem interface and utilities needed for WebAssembly host functions (ABI) such as WASI and runtime.GOOS=js.
The name sysfs was chosen because wazero's public API has a "sys" package, which was named after https://github.com/golang/sys.
